Front(7.50)

The EX-F1 provides a very deep, dimpled hand grip on the left side in a slightly rubberized material that contrasts with the overall hard plastic body. There’s a substantial indentation in the grip below the shutter to serve as a rest for your middle finger. This helps position your index finger in just the right shutter position as soon as you grab the camera.

Between the hand grip and the lens is a small green auto focus assist lamp. The large lens barrel juts out on the right side of the camera. At the top it’s labeled "EXILIM OPTICAL 12X", at the bottom the lens specs are spelled out. Above the lens is the word "Casio" printed on the angled front edge of the pop-up flash housing.

If not for the lack of a viewfinder hump,

you might mistake the EX-F1 for an SLR.

Back (6.25)

The 2.8-inch LCD screen takes up the lower left of the camera back, slightly raised with a smooth beveled edge. Centered over this display is the electronic viewfinder (EVF), surrounded by a fairly stiff rubber eyecup that protrudes about half an inch from the camera body.

To the right of the LCD is a cluster of black single-purpose buttons clearly labeled with silver text. On top is the EVF/LCD toggle control for shifting between viewing on the LCD and the electronic viewfinder. To the right of this button is a 12-dimple pattern that lets you know your thumb is properly placed for holding the camera without accidentally depressing the movie shutter button - this is an issue, as we’ll discuss later.

By default, when the camera is off, pressing either the Playback or Record button will turn the camera on in the appropriate mode, without a side trip to the ON/OFF button on top of the camera. This can be defeated via a menu setting if you prefer. These buttons can also be used to turn the camera off, though that’s not the default setting.

Below the EVF/LCD button is the DISP button, which controls how much information is displayed on screen or in the viewfinder. Next to this is the MENU button.

On the right is the movie shutter button, highlighted by a red dot in the middle. Around this shutter is a control that pivots into three positions: HS (High Speed), HD (High Definition) and STD (Standard). There’s a prominent bump sticking out from this control to let the user pivot it effectively with the ball of the thumb. This design has a problem, though, because it makes it more difficult to press down on the movie shutter lodged in the center: the bump gets in the way.

Unlike many cameras, you can’t shift from Playback to Record mode by pressing down on the shutter button. Instead, you have to press the small red Camera button. While the button is well placed under your thumb while holding the camera (assuming you have large hands), the shutter button mode swap is a faster way to grab a shot that comes up unexpectedly while you’re admiring your previous photos.

At the lower right of the camera back is an interesting control combination: a four-way controller, with a set button in the middle, surrounded by a rotating control wheel. In menu operations, camera settings or when scrolling through photos, the buttons and the wheel have the same function, moving you forward or backward through choices. If you’re moving a cursor a step or two down a menu, the four-way buttons work just fine. If you want to move quickly, though (particularly when scrolling through stored photos), the control wheel zooms through your options much faster.

The red button on the back is the movie mode shutter.

Left Side* (5.50) *At the back of the camera’s left side is a tethered snap-off port cover, which we can’t imagine opening successfully without fingernails (abandon hope, all ye nail-biters). Reseating the cover can also be a chore, since the plastic tether holding it to the camera tends to get in the way. When closed it’s reasonably secure, though we worry that rain could make it past the less-than-tight-fitting edges.

Under the cover are a power connector for an optional 9-volt adapter, a mini HDMI port for connecting an optional cable to an HDTV, a proprietary connector that does dual duty for both USB and AV connections, and a round plug for an industry-standard microphone.

The camera body has a handsomely sculpted shape that nicely combines secure handling practicality with aesthetic flair. The side narrows from full-width to lens-width by way of a curved body section. Within the crescent-shaped nook this design creates are three more camera controls: from front to back, Focus, Backlight Compensation (represented by a sun icon, with no explanatory text) and AE-L/AF-L (auto-exposure lock / auto focus lock). Above these controls "60 FPS CONTINUOUS SHOOTING" is boldly printed, and below the controls "DIGITAL CAMERA EX-F1" appears. All the text is printed in a metallic gold ink that manages not to appear gaudy thanks to the clear but slender typeface. The only fashion faux pas we spotted was a gaudy gold stick-on label printed with "FULL HD 1920 x 1080". Fortunately this one’s a sticker that can be removed.

The black eyelet for connecting a camera strap (a much better choice than the traditional silver given the camera’s overall look) sticks out quite far from the left side to make threading the loop easy.

The diopter control dial is located on the left side of the electronic viewfinder. It’s very difficult to turn, requiring fingernails and dumb luck to hit the desired position.

casio-ex-f1-left-375.jpg

Your left hand can readily access the focus,

backlight compensation and AE-L/AF-L controls.

Right Side*(7.25)*

The right side of the camera is largely taken up with the side of the textured hand grip. Behind this is a slide-back, pop-out door concealing the SD card slot. A patch with raised plastic bumps on the door makes it easy to open, but the solid latch and smooth fit of the edges along the door makes it unlikely you’ll open it accidentally.

Above this door is a black metal eyelet for attaching the camera strap. Unlike the left side eyelet, this one is recessed in a well in the camera body, which makes it exceedingly difficult to connect the camera strap.

casio-ex-f1-right-375.jpg

*The memory card slot door is secure yet easy to open.

*

Top*(7.50)*

On the right side of the camera top are two side-by-side dials. The one on the left is the CS (for Continuous Shot) dial, with six icons printed in silver and red. These represent, in clockwise order, Flash CF, Prerecord, High-Speed CS, Single Shot, Slow Motion View and Bracketing. Next to this is the Mode dial, with five settings: the unfortunately named BS (for Best Shot), Auto (an orange rectangle), A (Aperture), S (Shutter) and M (Manual).

Moving forward toward the front of the camera we encounter a small silver On/Off button, inset into the body so the top of the button is flush with the top of the camera, preventing accidental pushes. In front of this is the zoom control, with a prominent off-center bump in the front to catch your finger. The zoom control encircles a large silver shutter button.

*My what a big lens you have, EX-F1 - the

better to span 36mm - 432mm.*

Bottom* (6.25)*

The bottom of the camera features a metal tripod socket on the right, centered under the lens, and a latched battery compartment door. The tripod socket seems sturdy enough, though the ridged bottom of the camera attracts scratches when it butts up against the tripod plate.

The battery door is one more instance where fingernails are a necessity, but the latch does flip shut securely when closed. A small sliding clip keeps the battery from falling out accidentally when the door is opened.

It may look like an SLR, but at heart the EX-F1 is a rocket-powered point-and-shoot. The 1/1.8-inch CMOS image sensor, while tweaked for speedy performance, is much smaller than the sensor in an SLR, which led us to expect lower performance in lab testing. And while we did find color accuracy was sub-par even when compared to other point-and-shoots, we were pleased to find scores for resolution, noise and dynamic range that surpassed typical performance for other ultra-zoom cameras we've tested.

**Color **(5.71)

When you look at a photo and it just doesn't seem to capture the moment you remember, very often it's the color accuracy (or lack of it) that's putting you off. You were inspired by a particular blue sky, or green fields, or glowing cheeks, but when you look at the photo after the fact, the emotional impact suffers because the hues are off. Accurately assessing how color reproduction varies from camera to camera requires more than a good set of eyes – it takes a trip to the lab, with a consistent testing regimen. We photograph an industry-standard Gregtag Macbeth color chart at a wide range of exposure settings under studio lighting. The resulting images are tested using the sophisticated Imatest image analysis software to determine the difference between the known color values from the chart and the colors the camera recorded. The image shown below was produced by Imatest during testing of the EX-F1. It shows the original chart color (the small rectangle on the right in each box), the color captured by the camera (the outer rectangle) and the captured color corrected for luminance (the inner square).

casio-ex-f1-color-chart.jpg
color-guide.jpg
* * Accurate color reproduction isn't the strong suit of the EX-F1. While not terrible, the problem remains consistent throughout the range of ISO settings. We also found the images were significantly undersaturated, which gives colors a dull appearance. The following chart shows how a range of colors vary between ideal values (represented by the squares) and the colors found in photos taken with the EX-F1 (shown in the circles). The shorter the line, the more accurate the color.
casio-ex-f1-color-graph.jpg

*Shorter lines in this Imatest chart

indicate more accurate color reproduction.**

*

 There's a clear pattern here. Purples and reds are reproduced with very good accuracy, while blues, greens and yellows are pretty far off the mark. The good news here: flesh tones are likely to look about right, and that is an area where viewers are especially sensitive.




Casio EX-F1 Color Scores


casio-ex-f1-color-scores.jpg

The color performance score for the EX-F1 is compared here with the results for a similarly priced SLR, the Canon EOS Rebel XSi, and three long-lens point-and-shoots we've put through our lab testing. It's interesting that in this test, the point-and-shoots aren't necessarily at a disadvantage when compared to a pricier SLR. Still, the Casio is unimpressive, though on a par with the compact Olympus SP-560 UZ.

Resolution (8.04)

Image resolution and megapixel count don't necessarily go hand in glove. A camera boasting lots of megapixels on its sensor may still disappoint when it comes to the actual sharpness of the images it captures due to differences in optical performance, signal processing and other variables. That's why we shoot literally hundreds of photos of an industry-standard test chart (shown below) at several focal lengths, analyze them using Imatest and review the results in detail.

This resolution testing produces results measured in line widths per picture height (lw/ph), indicating how many progressively thinner, alternating horizontal and vertical lines on the chart the camera can reproduce before it all starts looking like a grey blob. The higher the number, the sharper the image.

casio-ex-f1-resolution-chart.jpg

The industry-standard resolution chart we use for testing

The best-case result for the EX-F1 was 1857 horizontal and 1734 vertical, shot near the wide end of the zoom lens range. Imatest indicated that rather than artificially boosting the perceived resolution through digital sharpening algorithms, the camera took a conservative approach, slightly undersharpening the image. The figures for the middle of the camera's extensive zoom range indicate continued strong lw/ph figures, though cranking the lens to its full telephoto setting did seriously impact results. Still, looking at enlarged photos taken even at maximum range, handheld in bright sunlight, the images deliver perfectly acceptable sharpness.

As seen in this comparison chart, the EX-F1 surpasses the long-zoom competition handily in most cases, though as expected it falls short when compared to the Canon XSi SLR, with its larger image sensor.

 




Casio EX-F1 Resolution Scores


casio-ex-f1-resolution-scores.jpg

Noise – Manual ISO*(8.93)*

Take a photo without flash in low light and look closely at the results. See the clumps and imperfections in solid-color areas? That's noise, an inevitable imperfection caused by the mass of circuitry required to take the light streaming through a lens and turn it into digital ones and zeros. While it's most noticeable in low-light photography and when making extreme enlargements, noise is a factor in every digital photo you take, to a greater or lesser extent. Manufacturers try to tame the beast by minimizing noise production on the front end, and digitally processing the sensor's initial signal to identify and remove noise before saving the file on the back end. Many cameras give you the option of turning that back-end noise reduction processing on or off. For the EX-F1 Casio decided to automatically use noise reduction for any shot taken at an exposure setting of 1 second or longer (time is one factor in increased noise production), and not to filter for noise at high ISO settings, which is another frequently employed technique. This automatically triggered noise reduction for long exposures can't be turned off by the user.

Our noise testing procedure calls for shooting color images at a range of ISO settings and having Imatest examine the results to determine how much noise each setting produces. These results are then graphed to reveal both the noise level and the rate of increase as light sensitivity ramps up. In the chart below, the percentage of noise in the captured images is shown on the left axis, the increasing ISO at the bottom.




Casio EX-F1 Manual Noise




 

casio-ex-f1-noise-graph.jpg

Despite its small sensor size, the EX-F1 produced exceptionally low-noise images at low ISO settings, though the graph does rise steeply as ISO increases. Overall we're impressed with this level of performance, particularly when compared to other cameras we reviewed. As seen in the chart below, the Casio surpassed the other ultra-zoom models in this benchmark test.




Casio EX-F1 Manual Noise Scores




casio-ex-f1-manual-noise-scores.jpg

Auto Noise (6.24)

In addition to testing by manually setting the ISO, we shoot using the Auto ISO setting, letting the camera pick its own level and scoring the result. In this case the EX-F1 shot at a reasonable ISO 200 and produced a good, if not outstanding, result. As seen below, the EX-F1 bested the point-and-shoot competition here and fell only slightly short of the Canon SLR. In practical terms, this test is less important than our manual noise testing, since it's a simple matter to set an appropriate ISO level while shooting and maximize the effect of the camera's low-noise capabilities.




Casio EX-F1 Auto Noise Scores


casio-ex-f1-auto-noise-scores.jpg

White Balance (5.08)

The actual color of light varies widely depending on the source. While our sophisticated brains do a wonderful job adjusting for this, perceiving essentially white light in all but the most extreme conditions, our cameras have a much harder time. They need to both accurately meter the color of incoming light and digitally adjust that value so that, in the final image, the scene looks the way we remember after mentally compensating for off-hues in the lighting. Not easy, and important to test. That's why we shoot under a variety of lighting conditions, including fluorescents, tungsten (i.e., light bulbs), photo flash and shaded daylight. In addition to automatically adjusting white to lighting conditions, most cameras offer preset white balance settings for a variety of sources, so the photographer can manually adjust when the automatic system doesn't seem to be producing accurate results. In the case of the EX-F1, the number of white balance presets is limited to six, and doesn't include a setting for flash (though it does accommodate two types of fluorescent bulbs). As a result, we tested manual white balance on three instead of our usual four parameters.

Auto White Balance (4.21)

We shot the Gregtag Macbeth color test chart under four types of illumination with the EX-F1 set to automatic white balance and ran the results through Imatest, which produced the chart below. It's important to note that the images shown here display intentionally exaggerated differences in white balance, to demonstrate the type of color shift you'd experience rather than the degree of color shift in real-world images.

The results here are a mixed bag. Under shaded daylight the automatic white balance delivers very good results (nearly identical to those using the manual preset, in fact). While fluorescent lighting proved difficult for the camera overall, the auto setting actually produced better results than either of the preset options. The auto white balance system didn't respond well to tungsten lighting, though, which represents a problem when shooting indoors with the EX-F1 under common household illumination.

*

Preset (5.96)

*Shooting the same color chart under the same lighting conditions, but using the camera's preset white balance values produced varied results. Using the preset dramatically improved performance under tungsten illumination – indoor shots will look noticeably better if you take the time to make this manual adjustment. Daylight shade results were virtually unchanged, which means they're pretty good with either auto of manual settings. And, as mentioned above, fluorescent lighting baffles both the manual and automatic white balance systems.

Still Life

To provide a side-by-side comparison of image quality, we shoot the same two still life scenes for each camera review. These photos are taken under standard fluorescent lighting with all camera adjustments set to automatic, at a range of ISO settings. The images of our happy (if somewhat stiff) married couple and a colorful still life below are clickable to open the full-resolution originals. These are multi-megabyte files, though, so they can take a while to download.

**Low Light **(5.60)

Flash photography is a great advance over no photography at all in the dark, but it has its antisocial aspects – aggravated party guests, crying babies – and the harsh illumination produced by on-camera flash often leads to the undesirable deer-in-the-headlights motif. That's why available-light photography is so important, and why we test a camera's low-light capabilities extensively. Low-light performance is also an important differentiating factor when comparing competing cameras head-to-head in today's market. Everybody has gotten better at shooting in low light, but some manufacturers have succeeded far more than others.

We perform two different types of low-light testing, one where the level of lighting is the variable, the other where exposure time starts at one second and stretches out to 30 seconds. The EX-F1 wasn't entirely accommodating on this last one, since the shutter speeds topped out at a modest 8 seconds with the camera set to ISO 400. While the shutter speed range actually stretches out to 60 seconds, the EX-F1 limits the exposure length based on ISO, throttling down the time as you boost the ISO – presumably because noise levels in long-exposure high-ISO shots would be unacceptable, though that’s only an assumption.

In our first test we set the camera to ISO 1600 (the highest available speed for the EX-F1) and varied light levels in our lab from a high of 60 lux (about what you'd find in a normal household environment) down to 5 lux (roughly the illumination from a single candle).

As shown in the chart above, the EX-F1 did well in our low-light testing considering its small sensor size, maintaining consistent exposure throughout the range of lighting condtions without gross color errors. Noise did climb as the lights dimmed, as expected, but the EX-F1 performance was in line with other point-and-shoot cameras we've tested.

To assess the camera's performance during long exposures we set the ISO to 400 and increase the shutter speed in increments till we reach 30 seconds, then analyze the camera's noise performance across this range. As mentioned above, the EX-F1 shutter speed range stopped at 8 seconds at ISO 400, so we shot three groups of test shots, at 1 second, 5 seconds and 8 seconds. This produced a flat response at an average noise value just over .835 percent, which is a good result, as might be expected given the camera's noteworthy performance in our other image noise testing.




Casio EX-F1 Long-Exposure Noise


casio-ex-f1-long-exp-graph.jpg

Overall low-light performance for the EX-F1 was slightly lower than some other point-and-shoot cameras we've tested, but not enough to produce differences that would be readily visible to the naked eye in real-world situations.




Casio EX-F1 Low Light Scores


casio-ex-f1-low-light-scores.jpg

Dynamic Range (7.13)

The EX-F1 did well in our dynamic range testing, particularly at the lower end of the ISO spectrum. There was a steep decline as we reached the ISO 400 level, but that deterioration leveled off well to produce respectably consistent results through the rest of the light sensitivity range.




Casio EX-F1 Dynamic Range


casio-ex-f1-dynamic-graph.jpg

The EX-F1 tested well versus other ultra-zooms, posting a significantly higher score, though it doesn't measure up to the performance of the Rebel XSi SLR.




Casio EX-F1 Dynamic Range Scores


 

casio-ex-f1-dynamic-range-scores.jpg

**Speed/Timing

**All speed tests for the EX-F1 were conducted using an 8GB SanDisk Extreme III SDHC card, shooting at the camera's top resolution and quality settings. To accomplish its extremely fast burst rate performance, the EX-F1 stores images first to internal memory, then asks user permission before storing the files to memory card.

 **Startup to First Shot **(0)

Considering its speed-demon reputation, this test proved something of a shocker. Turns out the time required to turn on the camera and get your first shot was far slower than other cameras we've tested. For example, the Canon Rebel XSi can squeeze off a first shot 0.98 seconds after hitting the power button, while the Canon PowerShot S5 IS takes 1.7 seconds. The EX-F1, on the other hand, requires several seconds to shake off the cobwebs after power-up before you can depress the shutter – on average in our testing, nearly 3.8 seconds. That may not sound like a lot, but when you grab the camera to capture baby's first step, you expect it to spring to life more quickly than this.

**

Shot-to-Shot **(14.00)

This is where the EX-F1 blows every other camera on the market, SLR or point-and-shoot, out of the water. In the lab it precisely lived up to its claim of 60 full-resolution frames per second (just a hair under 61, in fact). And while the occasions when shooting 60 frames in a single second are few and far between in most of our lives, you can set the interval between frames to suit your needs. We found that shooting swimming birds at 5 frames per second was a great way to capture just the right angle, while ramping up to 20 frames per second worked well when shooting sports action.

Shutter-Shot(3.76)

Aggravating delays between the moment you press the shutter and the moment the camera takes a picture are a rarity today. Surprisingly, though, the EX-F1 did not match the competition when tested in single-shot mode. The Canon XSi, for example, can squeeze off a shot with a delay of less than 0.2 seconds. For the EX-F1, we consistently measured the delay at over 0.5 seconds. While half a second isn't an eternity, it is long enough to miss a photo opportunity. The EX-F1 does have a workaround available in its prerecord continuous shutter mode. By holding the shutter down halfway in this mode, the camera shoots continuously and stores the results in a buffer. When you finally depress the shutter all the way, the prerecorded images along with those taken after you press the shutter are saved. Prerecord is undoubtedly a useful capability but it really doesn't make up for the lack of instant response in basic picture-taking operations.

Processing (8.24)

Digital cameras have a lot of work to do very quickly after you press the shutter, adjusting the raw data from the image sensor to reflect the settings you (or the camera’s automatic systems) have selected, running noise reduction algorithms, storing the resulting data to memory, and getting ready to take another shot. While all that’s going on, of course, you’re left looking at the LCD screen waiting to see how your shot turned out. We measure this processing time using a stopwatch program through repeated test runs. The EX-F1 performed respectably if not exceptionally well here, with an average processing time of just over a second.

Video Performance(8.43)

The score for the EX-F1 in this section is based on our standard lab testing suite, which measures color and resolution data with video taken at standard definition (in this case, 640 x 480). This multi-talented camera also shoots high-definition video in two formats, and high-speed video at three settings. We’ll discuss these separately, but they are not reflected in the numerical score.

Bright indoor light – 3000 Lux

This test involves shooting a test chart in a brightly lit lab environment, then analyzing the resulting video for color accuracy and image noise. The EX-F1 did well here, reproducing most colors well while producing the low-noise video we expect when there’s plenty of illumination.

casio-ex-f1-dumonde-1.jpg

casio-ex-f1-videoresult-300.jpg

Video color results at 300 lux

Low light – 30 Lux

A light level of 30 lux is still bright enough to read by, but not enough to produce flawless video reproduction even with dedicated camcorders. The EX-F1 held its own on this test, demonstrating the expected deterioration in color accuracy but maintaining a lower noise level than we typically find with still cameras in video mode.

casio-ex-f1-videoresult-30.jpg

Video color results at 30 lux

Resolution

Another component test in determining the overall video performance score requires testing the resolution displayed in multiple frame grabs from a test chart shooting. The EX-F1 stumbles here, failing to achieve adequate sharpness even with a well-lit chart. There is artifacting around the edges of objects, and stair-stepping visible on hard diagonal edges of objects in the frame.

Motion

The motion part of our test suite involves shooting a variety of fast- and slow-moving subjects and judging how accurately the video captures these diverse situations. While the EX-F1 results lack sharpness, this seems to be the fault of its resolution performance rather than being tied to the movement of objects in the frame.

High-Speed Video

It’s tough to pass judgement on the quality of video that you wouldn’t otherwise be able to shoot at all.  At 300 fps, video resolution is 512 x 384; at 600 fps, it’s 432 x 192, and at 1200 fps your window is just 336 x 96. From a pure quality perspective, we’re in the range of point-and-grab cellphone video. Focus is another factor that cuts into high-speed video quality: the EX-F1 has trouble with auto focus in the first place and, once you’ve started shooting, the focus is locked. Multiple trials did produce some interesting results (see ourYouTube video of high-speed hijinks below), but it’s novelty, not video quality, that makes it worthwhile.

High-Definition Video

Our biggest cause for concern with the high-def video we shot wasn’t with quality, but compatibility. When played directly from the camera on a 1080p plasma TV, though an HDMI cable, it looks very good, with nice sharpness and well-saturated colors. We’ve seen better quality from dedicated HD camcorders, but you can certainly impress an audience by playing your EX-F1 high-def video on a big-screen set.

Unfortunately, what you can barely do is edit your HD video on a computer, or even watch it on a PC or Mac. The Arcsoft software suite included with the camera offers Windows-based viewing of EX-F1 high-def video and rudimentary editing, but QuickTime, iMovie, Final Cut and other industry-standard programs refused to open the files we transferred to the hard drives of a Mac and a PC. Home video you shoot today is supposed to entertain you for years to come. If the file is non-standard to the degree these are, they fail the important test of time.

Viewfinder*(1.75)*

The electronic viewfinder, an 0.2-inch display with 201,000-dot resolution, appears large and clear enough, though we did find it difficult to see the entire screen at once while wearing glasses. The edges of the eyecup obstructed the view, creating a kind of tunnel vision that cut off the top and bottom, left and right edges. This is particularly troublesome since all of the menus appear in a strip at the far right side of the display. Without glasses, the problem disappears, but Lasik surgery shouldn't be required to use a camera properly.

On the plus side, viewfinder brightness can be adjusted to one of three levels based on user preference, and the settings make a noticeable difference. Another nice touch: you can overlay a nine-section grid over the shooting display, in the viewfinder or the LCD screen (through a setup menu choice), to help with horizontal and vertical alignment while shooting.

casio-ex-f1-viewfinder-375.jpg

The EVF is bright enough, but hard to use with glasses on.

******LCD Screen**(6.25)

The 2.8-inch LCD screen, with 959 x 240 resolution (230,160-dots total) provides an accurate view when it comes to image framing and color reproduction. It does get the grainy jitters when working in low light, but not enough to interfere with framing your shot. The screen can be set to four different brightness levels, either automatically (the camera senses ambient light and adjusts accordingly) or manually. We found the +1 setting was a good indoor/outdoor choice. It does become difficult to judge colors on screen when shooting in bright light, but seeing what you’re shooting is possible even in the summer glare.

Flash (8.50)

**The flash pops up automatically when settings require it. There is no physical button you can press to pop up the flash, or engage flash mode. This is unfortunate, since having to go through the on-screen menu is slower than simply pushing a flash button or lifting the flash into position, the systems used in most consumer-level SLRs with built-in flash. The height of the flash when engaged, at a full two inches above the camera body, is a big plus when it comes to avoiding red-eye when shooting in darkened rooms. While the flash pops up automatically, you’ll have to lower it by hand.

Casio gives the flash range as 1.6 to 22 feet (0.5 m to 6.7 m) at the widest angle setting, and 3.6 to 12.8 feet (1.1 m to 3.9 m) at the furthest telephoto. As expected, the flash can’t achieve the same range when shooting in continuous mode, at up to 7 frames per second. During continuous shooting the flash range is cut roughly in half, which is still impressive performance compared to the built-in flash in any other camera we’ve tested.

The red lamp next to the viewfinder flashes when the flash is recharging. If you’re shooting with flash, you’re locked out of taking a photo until the charge is complete. According to Casio, recharging the flash can take up to 9 seconds with a fully charged battery depending on temperature, but during our testing we never waited more than a second or two.

There are five flash settings: Auto flash, Flash off, Flash on, Red Eye Reduction and External Flash. ****Flash intensity can be set to 13 different levels, from -2.0EV to +2.0EV, in 1/3EV increments.****

For shooting movies, or stills at faster than 7 frames per second, the LED light can be turned on as a source of constant illumination. Pressing the bottom of the four-way controller turns the LED on and off while in movie mode, though this won’t work while shooting high-speed movies.

Flash assist can be turned on when a subject is not receiving adequate illumination in a dark setting. This feature uses an image processing algorithm to boost the brightness of the areas that are bright, but not as bright as they would be in a properly exposed image. Of course, this kind of processing noticeably increases image noise. We prefer tweaking the exposure in an image editing program, though point-and-shooters may be satisfied capturing an acceptable photo in difficult conditions with flash assist.

There is also an industry-standard hot shoe on top of the camera for connecting an external flash. You have to manually select External Flash (by pushing the four-way controller to the right) to avoid having the built-in flash pop up automatically, which is inconvenient.

Zoom Lens(7.00)

The EX-F1 doesn’t have that long snout up front for looks alone – it incorporates a powerful 12x optical zoom lens that ranges from 7.3mm to 87.6mm (equivalent to 36mm-432mm for a 35mm camera). At f/2.7 the lens is reasonably fast at the wide setting, though the maximum aperture plunges to f/7.3 at the full zoom setting, requiring plenty of illumination to take a sharp photo. The lens consists of 12 elements in 9 groups, including one aspherical lens. Image stabilization is handled through shifting the internal light sensor rather than optical lens elements.

casio-ex-f1-lens-mount-375.jpg

The EX-F1 zoom is equivalent to a 36-432mm lens on a 35mm camera.

A 4x digital zoom multiplier is also available, making the maximum theoretical zoom to 48x. Ordinarily, we just disable the digital zoom option when setting up a camera and leave it off. However, if you are shooting at 4 megapixels or lower with the EX-F1, you can employ digital zoom without lowering image quality, since the system can use a smaller pixel area in the middle of the sensor, producing a higher apparent zoom, without lowering final resolution. This can be useful when shooting movies, which are captured at lower resolutions than stills.

By default, the zoom lens is controlled using a side-to-side switch located around the shutter button. This zoom control is reasonably smooth and precise for a point-and-shoot camera, though it does jump unevenly from setting to setting at higher magnifications. We like the fact that, while you zoom, a numerical reading of the 35mm-equivalent zoom lens setting is displayed at the center left of the screen. Another nice feature is the option to program the ring around the lens barrel to work as a zoom control, just the way you'd work with a traditional SLR lens. There is a problem here, though: the ring isn't geared the way a zoom lens would be, meaning you get less zoom movement than you'd expect as you turn. That's great for fine adjustments, but for quickly zooming into the action, the standard zoom lever control is faster.

 

Model Design / Appearance*(7.50)*

This is one handsome camera, with an elegantly curved body that seems to be swooping forward toward your next photographic adventure. Of course, that impressive-looking 12x lens is part of the appeal, but we admire the way the glass has been integrated into the overall design to create a cohesive look. Even the few shiny flourishes, including the glossy panel on the top right of the camera and the button panel on the left, behind the lens, are fun highlights rather than intrusive design interruptions.

**

Size / Portability** (5.50)

The EX-F1 is a substantial piece of hardware, at 5.03' x 3.13' x 5.1' (127.7 x 79.6 x 130.1 mm) and a hefty 23.67 oz. (671 g.) without the battery. It may not have interchangeable lenses, but in shape and size it might as well be a digital SLR, meaning portability is not going to be this camera's strong suit, even compared to other ultra-zoom models. The Olympus SP-570 UZ, for example, with its 20x optical zoom, weighs just 15.7 oz. (445 g.).

Handling Ability(6.00)

Coming to grips with the EX-F1 requires some comfort compromises. The right-side hand grip protrudes roughly an inch and a quarter from the camera body. If you have large hands, that's enough to curl your fingers tightly around the grip, just touching the camera body between the grip and lens, shutter finger well positioned for stills, thumb securely on a dimpled area just right of the movie-mode shutter. In fact, one-handed shooting is very practical with this model, especially when using the LCD rather than the EVF for lining up your shots. Go for the two-handed grasp, though, and you may find finger traffic congestion sets in. Cradle the lens with your left hand and your fingers try to curl into the same indent where your right hand is holding the grip. We found the best two-handed hold required a little delicacy on the left side, basically crooking your index finger and resting the barrel on that. With a little practice this worked just fine, but it did take some fiddling to find that comfort zone, and it's hardly intuitive.

casio-ex-f1-holding-front-375.jpg
casio-ex-f1-holding-back-375.jpg

The EX-F1 is comfortable for one-handed shooting,

but a two-handed grip can be cramped..

**Control Button / Dial Positioning / Size **(8.25)

Even when you've found a comfortable grip, there's still the nagging problem of that movie shutter positioned on the back of the camera. After working with the EX-F1 for weeks we still hit that button accidentally far too often, sometimes when trying to shoot stills, sometimes just when carrying the camera around. Somebody at Casio made the design decision that being able to choose between shooting movies and shooting stills using separate shutters, without going through the extra step of changing modes with a menu or button selection, was the way to go. And yes, this arrangement does open up the possibility of shooting stills while recording movies. We just wish they'd found a better spot for the movie shutter – maybe over on the left side, where three buttons already find their home – so we wouldn't end up with quite so much video footage of our desktop, or the sidewalk, or the inside of the lens cap.

Other than that snafu, the controls are well designed and readily accessible. Very few buttons serve dual purposes, which makes the typical squinting for blue labels on a black camera body unnecessary. The combination four-way controller/ control dial on the back of the camera is a clever spin (literally) on the standard control scheme. For most operations, we still found ourselves pushing the controller sides up or down, left or right for most operations. However, when you want to whiz quickly through photos in playback mode, the control dial is a much faster solution. We like having this option, and appreciate the intuitive way it works.

The Function Ring around the lens barrel is another well-designed feature. It looks and feels like the zoom control of an SLR lens, and can be used for that purpose, but it’s actually a programmable control that can be assigned to zoom, or manual focus, or changing the continuous shutter speed setting on the fly.

casio-ex-f1-controls1-375.jpg

The combination of a central 4-way controller surrounded by a

spinning circular wheel proved very efficient.

Menu (7.50)

There are separate sets of menus for Play and Record mode, which is a mixed blessing: it keeps the display simple, but it does mean you can't change all the settings you might like in one place. In addition to the menus that take over the screen when you press the MENU button, the record mode for stills and movies also offers an always-on Control Panel strip menu down the right side of the screen that keeps frequently used adjustments, such as flash setting, ISO and white balance readily available. It's an arrangement that works very well in practice, since you never have to hunt for a buried menu setting or a particular button to make day-to-day adjustments while shooting.

The on-screen menu displays are well organized and easy to read, with white text on a gray background and a bright red highlight to indicate your position in the menu structure. A navigational problem does comes up when you want to move between two on-screen menu sections – from REC to Quality to Set Up while shooting, for example, Pressing right or left on the four-way controller opens the options for the item that's currently highlighted, but doesn't move you between menus. Instead you have to maneuver the highlight all the way to the top of a column before you can move between sections, which can be time-consuming.

Another navigational oddity comes when choosing from a sub-menu, such as the Anti-Shake setting or adjusting flash intensity. The instinctive way to do this is to highlight your selection and then press the SET button in the middle of the four-way controller. That works fine, but it also closes the menu system, when you may well want to make additional settings. To stay in the menu system and make more changes you're expected to simply highlight your submenu choice, then move left using the four-way controller to return to the previous menu. Getting used to this is a minor annoyance, granted, but the number of times we grunted a Homer Simpson 'D'oh!' during testing because the menu screen had disappeared unexpectedly indicates this wasn't the best design choice.

Ease of Use (5.75)

This is a relatively complex camera, with its multitude of modes and capabilities, many of which have never been seen before. In fact, it takes a 185-page manual to explain it all, which unfortunately is provided only as a PDF file and not a printed document. We’re not big fans of grinding up trees unnecessarily, but in this case the manual is required to take full advantage of your $1000 purchase, and computer-based manuals don’t travel well when you take your camera out to shoot. And if you’re going to create a 185-page manual, wouldn’t it make sense to include an index?

Beyond documentation issues, using the EX-F1 is pretty easy once you get the hang of it. The dual control-dial system on top of the camera – one for exposure modes, one for shooting modes – organizes choices well. Similarly, the three-position selector around the movie shutter makes changing between standard movie, high-def movie and high-speed movie modes crystal clear.

Auto Mode (3.50)

While many cameras today feature a Program mode that automates exposure control and an idiot-proof Automatic mode that takes over virtually all of the camera’s controls, Casio makes due with a single mode it calls Auto, which is equivalent to what most manufacturers label 'Program.' Leave the camera set to Auto and you're still responsible for setting ISO, white balance, metering pattern and auto focus pattern, which other cameras generally handle when a user chooses the Auto mode.

Movie Mode (10.25)

The EX-F1 offers three distinct movie modes for starters, with a dazzling, perhaps dizzying array of choices within each.

Standard Movie Mode: With the Movie Mode Selector switch set to STD, movies are shot with a 4:3 aspect ratio, 640 x 480 resolution, at 30 frames per second. The maximum movie size is 4 gigabytes, which works out to nearly three hours. Best Mode presets are available, along with sensor-shift anti-shake, though face detection is turned off. The built-in stereo microphones are used, or you can plug in an external mic. The special YouTube capture mode allows lower-resolution video capture (432 x 192, 512 x 384) without audio, along with standard-resolution video with stereo soundtrack.

High Definition Movie Mode: With the Movie Mode Selector set to HS, the EX-F1 shoots in 16:9 format with resolution set at either 1280 x 720 (30 frames per second) or full HD (1920 x 1080, 60 fps). Here again, you have your choice between built-in stereo mics or an external mic.

High-Speed Movie: Flip the switch to HS and you’re ready to shoot your own personal Discovery Channel special, at speeds ranging from 30 frames per second to an astonishing 1200 fps. Of course, as you push the speed higher, the resolution creeps down to the point where you have to question the practicality of the whole thing. At 300 fps, the movie is shot at 512 x 384; at 600 fps, you’re down to 432 x 192, and at 1200 fps you’re shooting a 336 x 96 video sliver. You still have access to aperture-priority, shutter-priority or full manual exposure control, though focus remains fixed at the moment you press the movie shutter (then again, how far can your subject move in a fraction of a second?).

While shooting standard or high-def movies, you can also capture up to 20 snapshots by pressing the shutter button.

Drive / Burst Mode*(9.00)*

Continuous shutter modes, along with time-warped movies, are where the EX-F1 crosses over from cool tech into near-science-fiction. Grab up to 60 high-res stills per second. Capture up to 7 shots per second with the flash firing. This is technology that leaked out of Area 51 and somehow landed at Casio headquarters, ready to tantalize anyone from serious sports photographers to proud Little League parents.

Let’s look at these high-speed modes individually and explore the options in depth.

High-Speed CS: Three variations are available:

For any of these modes, the camera ring control can be used to change the frame-per-second rate on the fly if you specify this control assignment in the set-up menu.

Flash CS: This continuous shooting mode uses either the flash or the LED light for illumination. The flash can fire up to 7 times per second; you can set Flash CS mode to take from three to 20 shots consecutively. For even faster shooting, the LED light is used to provide continuous illumination, and you can record between one and 60 shots.

Prerecord: Press the shutter button halfway down and the camera starts taking photos and storing them in a buffer (this works for both still and movie modes). When you fully depress the shutter, the camera starts shooting continuously and then, when the combination of shots taken before and after the shutter press equals sixty seconds, both are stored to the memory card. You get to decide how much of the time should be allocated to buffer and how much to shoot after pressing the shutter. The big idea: instead of worrying about catching just the right moment to press the shutter and capture an image, you do your best secure in the knowledge that, even you’re a little late, you’ll still get the shot.

Slow Motion View: Conceptually complex but potentially interesting, this view stores images into the buffer when the shutter is halfway depressed, and plays them back at slow speed (up to two seconds worth of images are in the buffer at any given time). When the photo you want to capture appears on screen, press the shutter completely and all the images in the buffer are stored to the memory card.

All of these continuous shooting modes require setting the camera to Auto mode.

Bracket: Three different types of automatic bracketing are provided: exposure, white balance and focal distance. Each bracketing option provides the choice of 3 or 5 shots. For exposure bracketing, you set the bracketing amount in 1/3EV increments. White balance and focus bracketing each offer two increment ranges, though unfortunately there’s no indication of the degree of change being implemented. Flash isn’t supported during bracketed shooting.

**Playback Mode ***(8.75)*

Still images can be displayed in four ways, toggling between them using the DISP button.

  • Full-screen image with basic shooting information (file name, image size, date and time taken, plus battery charge indicator)

  • Same as above, but with overexposed areas highlighted

  • Additional overlay with focal distance, exposure compensation and white balance settings, flash mode, focus area, ISO, aperture, shutter speed and a histogram to display the distribution of exposure values in the image. While better than nothing, the tiny size of the histogram limits its practical benefit.

  • Clean screen showing image alone.

 When shooting using Continuous Shutter mode, the camera compiles the captured images into a group for playback purposes. This allows you to delete single images or an entire group of images at once if you choose. Alternatively, you can divide up the group into individual images through the playback menu.

Pressing the zoom control toward the telephoto side displays up to 8x magnification during playback. Pressing the zoom control in the opposite direction brings up a 12-image thumbnail display which can be navigated using the four-way control or control wheel, hitting the Set button to choose a photo for full-screen display.

The slideshow utility, accessed via the Play menu, provides user-selected interval timing, total playback time, and five combinations of between-image effects and background music.

Movie playback offers forward and backward playback at multiple speeds, zoomed-in viewing and audio volume adjustment. The information display toggles between a clean full-screen display and an overlay with file name, movie length, shooting mode (standard, high-def of high-speed), date and time plus battery charge indicator.

It’s possible to capture stills from stored movie files in playback mode. This function, called Motion Print, will either save a single movie frame of your choosing as a full-screen image, or create a nine-frame montage with your selected frame in the center and additional frames before and after that one in strips at the top and bottom of the image.

motionview.gif

 

 Basic in-camera movie trimming is also supported. During movie playback, use the four-way controller or control dial to find the spot where you want to edit. You then have three choices: trim away everything from the beginning of the movie to your current location, delete everything after the current location, or remove everything between two points (you’ll be prompted to find the second point after selecting this option). It isn’t possible to re-order sections of a movie or combine pieces from different files – this is strictly a trimming feature. And there’s an important caveat before using this option: only the edited result is saved, not the original file. There’s a kludgy workaround: you can create a second copy of the file to the camera’s built-in 31.9-megabyte memory if your movie fits. It would have been much more logical to save both the original and the edited version in the first place, though, a procedure the camera follows automatically for in-camera still image editing operations.

**

Custom Image Presets***(12.00)*

Casio calls its preset system Best Shot, labeled BS on the mode dial. There are 26 already programmed, most of which apply to both still and movie shooting, from the expected portrait, sports and scenic vista settings to some more esoteric choices including "eBay" for shooting items for auction and "Food" (high-saturation macro). For each Best Shot mode, pushing the zoom control brings up a short text block explaining how the settings work, a nice touch.

The Digital Anti Shake mode is unusual. It records multiple images and automatically combines the sharpest sections to correct for image blur. Digital panning is another technologically sophisticated choice, again shooting and combining several images to create a photo with the foreground subject in sharp focus against a motion-blurred background. There’s a Move Out CS mode that automatically starts shooting multiple frames when the subject moves out of a user-defined on-screen frame, and Move In CS which starts shooting when the subjects enters an on-screen frame. There’s also a preset mode optimized for shooting YouTube videos, which are stored in a separate folder on your memory card to make them easier to find.

Finally, if there is a set of adjustments you particularly want to have at your fingertips in the future, it’s easy to create your own Best Shot mode. Simply select a photo you’ve taken with the desired settings, then register it as a scene mode selection. There’s room for up to 999 user-created entries, each of which includes settings for face detection, focus, EV shift, white balance, flash, ISO, metering, dynamic range, flash intensity, flash assist, color filter, sharpness, saturation, and contrast.

Manual Control Options

The EX-F1 offers aperture-priority, shutter-priority and full manual shooting. The metering system makes them difficult to use, though. Instead of offering a live on-screen display indicating the current metering as you adjust the aperture or shutter setting, all you see is the setting you’re manipulating in green on-screen text. Then, when you press the shutter half-way, the camera takes a meter reading, sets the shutter speed and ISO, and lets you know whether you’ve hit an acceptable combination by displaying ISO, aperture and shutter readings numerically. If the type is white, you’re alright. If the type is orange, your settings are bad, though there‘s still no indication of how far off you might be from the camera‘s idea of an ideal setting, making further adjustments another hit-and-miss proposition. This guesswork approach to manual control is so inefficient that it will discourage newbies and experienced shooters alike from moving the mode dial off Auto.

Values for Sharpness, Saturation, and Contrast are adjustable through the Record mode Quality menu, each offering two steps up and two steps down from normal.

Focus

The Focus button on the lens barrel toggles between four modes:

  • Auto Focus, available in the range from 1.3 inches to infinity

  • Macro Focus, available from approximately 2.0 inches to 19.7 inches

  • Infinity Focus, which sets focus for landscape and other distant subjects with one press

  • Manual Focus, from 2.0 inches to infinity

Auto Focus (8.75)

There are three auto focus modes, each of which basically uses a small focal spot, but in different ways. The basic spot focus mode concentrates on the small area in the center of the screen. You can always use focus lock to aim at an object in the middle of the screen, focus on it by holding the shutter down halfway, then move the camera to recompose the image without changing the focus setting.

The Free focus mode overlays a visible crosshair pattern on the viewfinder and lets the user move the point of intersection up and down, left and right to select a point anywhere on the screen as the focal point.

Finally, Tracking mode focuses on the object in the middle of the screen when you half-press the shutter button, then automatically maintains focus on that subject as it moves, as long as the shutter button remains depressed. There are a few picture modes where Tracking isn’t available, including still image prerecord, slow motion view, and YouTube.

Continuous Auto Focus is also available in all three modes. When enabled, this feature maintains focus even when you don’t keep the shutter button half-depressed.

There is an Auto Focus Assist Light to the left of the lens which illuminates automatically when the shutter is depressed halfway in dim lighting situations.

The EX-F1, sad to say, is auto focus challenged, particularly in low light situations. We frequently found that the system refused to focus the first time we held the shutter down, only to lock in quickly and efficiently when we pressed it a second time, with no change in position or settings. There’s no rhyme or reason to the problem. It is worse when the lights or low, but even an outdoor scene with clearly defined edges can suffer from focus interruptus.

Manual Focus (7.75)

During manual focus operations, a yellow box appears on the monitor. Focusing is controlled using the left and right sides of the four-way controller. When you start to focus, the area within the yellow box enlarges to full-screen to make details easier to see (the display returns to normal after remaining idle for two seconds). If you prefer, you can use the set-up menu to set the lens barrel ring to control manual focus. We found this much smoother and more instinctive than using the four-way controller, and recommend making the change.

ISO (7.50)

There are five ISO settings, 100, 200, 400, 800 and 1600, plus Auto. Some odd restrictions turn up regarding ISO when you read the fine print, though. When shooting RAW, the maximum ISO setting is 200, for no apparent reason. Also, when shooting movies, Auto ISO is always used.

White Balance (6.50)

In addition to the default Auto WB setting, which lets the camera set the white balance based on live readings while shooting, there are also six user-selectable white balance presets: Daylight, Overcast, Shade, Day White Fluorescent, Daylight Fluorescent and Tungsten (i.e., light bulbs). You can also set a white balance value by selecting Manual WB from the white balance menu, aiming the camera at a white piece of paper and pressing the shutter button.

Exposure(7.25)

The EX-F1 offers aperture-priority, shutter-priority, full manual and auto exposure modes. Exposure compensation is available from the main Control Panel menu in the -2.0EV to +2.0EV range, in 1/3EV increments.

One-button backlight correction is also available by pressing the middle button on the lens barrel. This choice combines exposure shift with dynamic range adjustment to compensate for an underexposure caused when a dark subject is positioned in front of a bright background.

The AE-L/AF-L button is programmable through the menu system to lock either exposure, focus or both when pressed.

We found that, when left in auto mode, the EX-F1 frequently blew out highlights, even when the range from dark to light wasn’t all that challenging. Seting exposure compensation to -1/3 nearly always solved the problem without excessively darkening the image, but we expect the auto exposure setting to handle that chore.

**

Metering** (8.50)

The EX-F1 supports three metering modes, accessible via the Control Panel. Multi-pattern metering analyzes the entire image area to create an exposure setting that maintains an overall balance. Center-weighted, as the name implies, favors achieving proper exposure in the middle of the frame. Spot metering reads only the small central area of the image and sets exposure value accordingly.

Shutter Speed (10.00)

The shutter speed specs for the EX-F1 are unlike any other camera we've seen. Yes, you can take long exposures up to 60 seconds, but you can also shoot at 1/40000th of a second thanks to the system’s unique high-speed technology. When shooting single-shot stills in Auto mode the shutter speed range is a bit more traditional, maxing out at 1/2000th second. And as noted in the testing section, the camera puts hard limits on the selectable slow shutter speeds based on ISO values. While a 60-second exposure is allowed at ISO 100, you’re limited to 8 seconds at ISO 400 and 1 second at ISO 1600.

Aperture (8.50)

Aperture settings range from f/2.7 to f/7.5 at the widest end of the zoom range and f/4.6 to f/13.1 at the maximum telephoto setting. That represents respectable light sensitivity at the wide setting, though the telephoto side of the range isn't up to our expectations. The Olympus SP-570 UZ, for example, is a 20x ultra-zoom model ranging from 26-520mm (35mm equivalent), yet still delivers a maximum aperture of f/4.5 at the top of its telephoto range.

Picture Quality / Size Options (6.00)

Stills can be shot in seven sizes plus RAW:

 RAW shooting is only permitted in single-shot mode, is only available paired with a JPEG file, and that file must be at maximum resolution.

**

There are three image compression settings, Fine, Normal and Economy.

Higher-res images can be resized in the camera to 3M, 2M and VGA sizes. In-camera cropping is also available.

Picture Effects Mode** (5.00)

The EX-F1 offers eight color filter options: B/W, sepia, red, green, blue, yellow, pink and (for you Prince fans), purple. There is no option to increase or decrease the intensity of the effect, though.

Image sharpness, color saturation and image contrast can also be adjusted during shooting. Each supports a range of five settings.

Several parameters can also adjusted in-camera for a shot you’ve already saved to memory card. The full selection of white balance settings is available as an image adjustment in playback mode. Image brightness can also be fine-tuned (five settings are available). In-camera image resizing is supported, saving to either 3MP, 2MP or VGA (640 x 480) size, along with in-camera image cropping. The good news for all these editing options is that both the original and the altered image are automatically saved as separate files.

Connectivity

**Software (2.00)

Casio supplies a CD with two or three programs (depending on how you count), for Windows users only. The YouTube Uploader streamlines the process of sending photos to the ubiquitous social networking site, and works seamlessly with photos taken using the YouTube Best Shot mode. The remaining software is two-part suite from ArcSoft including TotalMedia Theatre and TotalMedia Extreme. The Theatre program allows you to play back high-definition video shot with the EX-F1 and, sometimes, capture still images from that video (this apparently works on computers running Windows XP but not Vista). The TotalMedia Extreme program allows basic video editing and creation of AVCHD DVDs that will run in suitably equipped DVD and Blu-ray players. While the software is good enough for basic chores, it doesn’t fix the underlying compatibility problems we encountered. The camera produces .MOV files which we were unable to open in QuickTime (on Mac or PC) or several other video playback programs.

Jacks, ports, plugs (5.50)

On the left side of the camera, under a rubber door, are connectors for an optional external power adapter, a mini HDMI cable (not included) for viewing high-def video (with sound) on an HDTV, a proprietary connector for USB and standard-definition AV output (both cables included) and an external microphone (again, mot included). High-def video output should automatically adjust to match the specs of a connected TV through HDMI – it worked in our tests. However, it’s also possible to manually set the output resolution to 1080i, 480p or 576p (for PAL sets).

The potentially useful connection missing here is component output, which is supported by virtually every high-def display or device, even those that do not offer HDMI connectors.

casio-ex-f1-ports.jpg


*The left-hand panel supports (from top to bottom)

power in, HDMI out, USB/AV and external mic.*

Direct Print Options (3.00)

The EX-F1 is compatible with PictBridge-equipped printers, allowing direct output without using a computer. This is a barebones implementation of PictBridge printing, allowing paper size and number of prints selection, but not more advanced features such as creating an index print of thumbnails.

DPOF, which allows you to create a predefined print order to be used when printing through your computer or from a professional print service, is also supported. You can specify the number of prints you want for each individual image and whether you want the time and date stamp included in the print, but again no advanced features are provided.

Battery (7.00)

The FX1 uses a Casio NP-100 lithium-ion rechargeable battery rated at 7.4V, 1950mAh. The manufacturer claims 520 shots, 8 hours of continuous snapshot playback or 3.5 hours of continuous movie recording per charge.

casio-ex-f1-battery3.jpg

*Casio claims a 520-shot life for this

lithium-ion battery.*

Memory (4.00)

The EX-F1 accepts SD and high-speed SDHC memory cards along with the less common MMC and MMCplus format cards.

casio-ex-f1-memorycard.jpg

The EX-F1 works best with high-speed

SD and SDHC memory cards.

Other features (5.50)

Image Stabilization – *Casio employs two strategies to deal with camera shake. What they call Camera AS (Anti-Shake) employs sensor-shift stabilization to counter the effect of shaky hands. Camera AS is available in both still and movie modes. Image AS, which applies to still photography only, controls ISO settings in an effort to boost sensitivity, hence increase shutter speed and minimize the effect of movement. Choosing Auto deploys both techniques simultaneously. We found the anti-shake system worked well when shooting stills using the telephoto capability, but our handheld long-distance movie attempts could serve as ads for Dramamine.

Face Detection – *The EX-F1 face detection software sets focus and exposure based on one or more faces it finds in the frame. *

Remote Shutter Release – An unusual extra included in the bundle, the wired remote shutter release comes in handy when shooting on a tripod. The cord, at six and a half feet, offers some welcome freedom to move around while shooting. The remote shutter release plugs into the USB/AV port on the left side of the camera.

Dynamic Range Compensation - *While shooting, the EX-F1 offers two levels of dynamic range compensation to minimize over- and under-exposure.

Value*(7)*

This is usually an easy section to assess, but this camera is so unprecedented that how much is worth is very much in the eye of the beholder. We got tired of the slow-mo movie feature quickly – you might find shooting Mentos hitting Diet Coke in exquisite detail endlessly fascinating. The standard-definition movie mode is better than some cameras we’ve tested, but nothing exceptional, and certainly doesn’t compare to what you’d shoot with a dedicated camcorder. As for the high-def movies, we like the look but hate the compatibility problems. That leaves us with the one feature we find irresistible: shooting lots of stills very, very quickly, a capability even our favorite SLRs simply can’t match. That’s why it’s going to hurt sending our review unit back to Casio, and why we’re giving the EX-F1 a high score in this category. At the same time, though, we’re inclined to wait till the next camera incorporating these technologies before dinging our own credit cards with a purchase.

Comparisons

Inevitably, trying to compare a unique multitasking device like the EX-F1 with existing products on the market is going to read a little like the old story of the blind men trying to describe an elephant when each is touching a very different part. Still, for the price of an EX-F1 you could buy a highly rated digital SLR and probably an extra lens to boot. And if it’s high-quality long-lens digital photography you’re after, plenty of solid cameras are available at a fraction of the price. With the unique characteristics of the EX-F1 as a given, let’s compare it against the strengths of four other cameras when it comes to tackling traditional photographic tasks.

**Canon Rebel XSi – **This low-cost digital SLR ($830 with the 35-70mm kit lens) outperforms the EX-F1 soundly when it comes to color accuracy, resolution, white balance, low-light performance and dynamic range (though interestingly enough, not in noise performance). The ability to use interchangeable lenses from a host of major manufacturers translates into a wealth of photographic possibilities, and manual controls are far more sophisticated than those provided by the Casio. Of course, the XSi has no video mode at all, a long-zoom lens is an extra-cost purchase, and burst mode tops out at 3.5 frames per second, which used to sound impressive.

Canon PowerShot S5 IS – With a list price of $499, the 8-megapixel S5 IS boasts a 12x-zoom lens with optical image stabilization, a very good movie mode and high scores for color reproduction and white balance accuracy (though image noise and dyamic range didn’t measure up in lab testing). Its 2.5-inch LCD folds out and rotates to provide additional comfort and flexibility while shooting.  Burst mode is nothing to write home about, though, at 1.5 frames per second, and at nearly a pound, it lags behind other ultra-zooms in portability.

Olympus SP-560UZ–It weighs in at a svelte 12.9 ounces (versus 23 ounces plus for the EX-F1), even with an 18x zoom lens. With 8-megapixel resolution (versus 6MP for the EX-F1), the SP-560UZ lists for $499, and is widely discounted. The image stabilization system effectively combines optical and sensor-shift technologies, making it a superior performer for those handheld long-zoom shots. And when it comes to low-light photography, this Olympus model goes all the way to ISO 6400, albeit at reduced resolution. When it comes to our lab testing, the 560UZ was bested by several other ultra-zooms, but rarely by the EX-F1.

Panasonic Lumix DMC-FZ18-  The lowest-priced choice here, at $399 list, the FZ18 nevertheless provides an 18x optical zoom lens, RAW image capture, high-quality video capture and extensive manual control capabilities. The Panasonic shares the EX-F1s dislike for low-light autofocus, but proved far superior in reproducing colors accurately. And when it comes to portability it’s no contest: the Panasonic weighs in at 14.4 ounces with battery, and measures a modest 4.63 x 2.96 x 3.47 inches versus the Casio’s beefy 5.03 x 3.13 x 5.12 inch body.

Who It’s For ***

Point-and-Shooters – Yes, you can use the EX-F1 simply, and the fact that you can shoot large quantities of images first and figure out what came out well later can cover up a multitude of photographic technique shortcomings. On the other hand, this is a bulky piece of equipment to carry around, and much smaller cameras with even greater zoom lenses are available for far less money.

Budget Consumers – At $1000? Not a chance.

Gadget Freaks – *It just doesn’t get much better than this. Amuse yourself with dials and controls and modes galore, enjoy the photo and video results and, most important, show off your Jetsons camera to all your friends.

*

Manual Control Freaks – *It’s possible, but the manual control implementation is clumsy and limited. *

Pros/ Serious Hobbyists – *Six megapixels does not a pro camera make, and there are image quality and control limitations. Still, if you’ve got the extra cash, it’s hard not to buy a camera that will help you catch the one that got away as frequently as the EX-F1 will.

Conclusion**

casio-ex-f1-vanity-180.jpg
Casio's EXILIM EX-F1 promises features no digital camera on the market has offered before, and it delivers - with some reservations. The camera's strongest suit is the option to shoot up to 60 full-res 6-megapixel images in a second. Combined with a sophisticated prerecord capability that continually captures images to a buffer when you half-press the shutter and saves the most recent ones to memory when push the shutter all the way, the tools you need to never miss another great shot are at hand. Image quality wasn't great, but it's perfectly acceptable for on-screen viewing or consumer-size prints. The other headline feature is capturing movies at incredible speed -- as many as 1200 frames per second, producing a slow-motion effect previously found only in science lab experiments. We loved this for a day or two, but it lost the ability to raise a giggle pretty quickly. Of course, your smileage may vary.

There are ultra-zoom cameras that are far more portable, and available at far less than the $999 price of an EX-F1, or you could opt to spend a grand on a high-quality digital SLR with superior image quality and the option to use interchangeable lenses. That's our practical side talking. When it comes to having fun with a digital camera, the EX-F1 has no equal.
