As for Panasonic's own Micro Four Thirds lenses. there are currently six options, including the two kit lenses available bundled with the GF1 body. We expect most users will opt for the DMC-GF1K package, priced at $899.95, which includes a 14-45mm f/3.5-5.6 zoom lens (equivalent to a 28-90mm on a 35mm camera). There's another intriguing option, though, at the same price: a slender 20mm pancake lens at a speedy f/1.7 maximum aperture. This is a potent combination, particularly those of us who prize portability and low-light capability. Unfortunately, we were unable to get a pancake lens in for testing.

The GF1 offers two types of digital zoom, neither one of which is especially useful. Extended optical zoom increases magnification when shooting at small and medium image sizes by using only the center portion of the sensor. This doesn't affect picture quality; it's basically the same as cropping down to the center of a full-res image in a photo editing program (but with less creative flexibility). There are also 2x and 4x digital zoom settings, which are the usual quality-be-damned mathematical enlargements and best left unused.

The GF1 sensor has a gross resolution of 13,060,000 pixels and an effective resolution of 12.1 megapixels. The Micro Four Thirds sensor format is both a blessing and a curse. With a compact camera body like the GF1, the fact that the 17.3 x 13mm sensor is nearly 10 times as large as the typical point-and-shoot camera, enabling higher resolutions with lower image noise and wider dynamic range. Conversely, though, if you're comparing a Micro Four Thirds camera against the typical APS-C sensor found in most digital SLRs, image noise is likely to be higher, and the wide angle coverage provided by the same size lens won't be as extensive. When figuring the equivalent optics of a lens in Micro Four Thirds format, you double the millimeter measurements: that is, the 14-45mm lens provided with the GF1 is equivalent to a 28-90mm lens on a 35mm camera. A 14-45mm lens mounted on an APS-C sensor camera, on the other hand, has only a 1.6x magnification factor (roughly 22-72mm), a gain on the wide angle side of the range and a lower maximum telephoto.

The automatic dust reduction system kicks in whenever the camera is turned on, and can also be performed at will by choosing Sensor Cleaning in the Custom menu.

The GF1 doesn't come with a viewfinder, but it is compatible with a slick optional electronic viewfinder, priced at $200. The DMW-LVF1 attaches to the hot shoe (a plug slips into a dedicated electronic connection on the back of the camera) and recreates the Live View display in miniature. The viewfinder can also be set at an angle (up to 90 degrees), a benefit of its unusual mounting. This contrasts with the Olympus E-P1, which offers only an optical viewfinder accessory, priced at $100, that displays the scene as it would be seen through the 17mm pancake lens.

The LCD screen is a 3-inch 460,000-dot display that looks particularly sharp when reviewing your shots. It looks fine when shooting in well lit areas, but when the light gets low, the refresh rate gets slow, leading to stuttering and even some blurring as you pan.

The LCD screen (along with the optional electronic viewfinder) can be adjusted to one of seven brightness levels. In addition, there are two optional modes for adjusting screen brightness to fit the shooting environment: Auto Power LCD reacts to detected light levels, while Power LCD turns brightness to full blast, useful when shooting outdoors.

LCD color saturation and color reproduction (along a yellow-magenta axis) also offer seven settings.

Secondary Display

The monochrome LCD found on higher-end traditional SLRs to display camera settings when viewed from above is a rarity even on most consumer SLRs, and absent as expected on this slender Micro Four Thirds model.

The mono LCD display is small and disappointing.

The GF1 and the Olympus E-P1 are near-twins when it comes to size and shape, but Panasonic figured out how to include a pop-up flash in their compact package, and Olympus didn't. And it's a pretty good little flash at that. Press a button on the back of the camera and it leaps to attention, both above and slightly in front of the camera body, to offer a clearer path past a protruding zoom lens. The autoexposure system can't pop up the flash on its own, which we far prefer; far less likely to accidentally fire off a blast where it's prohibited by regulation or common sense.

Panasonic gives the flash range as 3.28 feet to 5.58 feet (1m to 1.7m) when shooting with the kit lens at its widest setting, at ISO 100. That's not a lot of illumination. However, the flash illumination pattern is surprisingly even, with little of the central hot spot problem we expect to see in a small strobe. Maximum synch speed when shooting in auto flash mode is 1/4000 second, though it's capped at 1/160 second in forced flash mode.

All the flash controls you'd expect in a well-outfitted SLR are included, with various combinations of auto flash, red-eye reduction, forced flash, and slow sync. When not using red-eye reduction, the flash can be set to second curtain sync, which produces a trailing light effect when shooting moving cars and similar subjects.

Flash output can be manually adjusted, in a ±2 EV range, in 1/3 EV increments.

Flash Photo

The flash emitter pops up from the top of the body via a mechanical release.

Beneath a hinged door on the left side of the camera are three connectors. The round one on top is used for the optional DMW-RSL1 wired remote control ($80). There is no wireless remote available for this camera.

For video output, there's both a proprietary standard-def AV cable connection (at the bottom of the compartment) and a mini HDMI out port (no cable provided) above it. The HDMI output ordinarily switches to match the resolution of a connected TV automatically, but if necessary the user can manually choose from 1080i, 720p or 480p. Panasonic high-def TV owners get a bonus when connected via HDMI: the TV remote can control camera playback.

The GF1 runs on a DMW-BLB13PP Lithium ion battery rated at 7.2V, 1250mAh. Panasonic gives the number of exposures per charge at 350 pictures, testing according to CIPA standards. This sounds about right to us, and we find this performance impressive, given the constant use of the power-sucking Live View display. Charging time is approximately 155 minutes.

We were impressed with the overall image sharpness of the GF1; even with the lens stopped own all the way, the test results are strong, The best sharpness result was measured in the center of the lens when shooting at the widest focal length. With the lens wide open, we measured 1867 lwph horizontally and 1972 lwph vertically. More on how we test sharpness.

Overall, the GF1 image stabilization system, using the kit zoom lens, was unimpressive. It produced marginal improvements at slow shutter speeds with high camera shake, but doesn't measure up to the tested performance of other cameras, including its brand mate GH1.

To test image stabilization, we mount the camera in a custom-designed computer-controlled rig that produces controlled movement patterns. We run separate horizontal and vertical movement tests, each at both a high and low camera shake setting. By comparing the resolution of test images taken with the image stabilization system turned on with those taken with image stabilization off, we can determine the system's effectiveness at reducing blur.

The Panasonic GF1 produced more accurate color than the GH1, but still fared poorly against the Olympus, Canon and Nikon competition. We shoot the X-Rite ColorChecker chart in each available color mode under controlled studio lighting. The resulting images are analyzed using Imatest software to determine which setting produced the most accurate color reproduction. That mode is used for scoring purposes. More on how we test color.

The GF1 offers nine film modes, six in color and three in black and white. The Smooth mode produced the most accurate results, slightly undersaturated at about 96% and with spot-on hues for the dark skin, foliage, blue flower and purple color patches. However, the yellow and yellow green reproduction were way off the actual color values, with cyan and orange also significantly off.

The following chart shows same size crops of each color patch from the test chart, shot in the most accurate mode for each comparison camera.

NOTE: Because of the way computer monitors reproduce colors, the images above do not exactly match the originals found on the chart or in the captured images. The chart should be used to judge the relative color shift, not the absolute captured colors.

As seen in the chart, the Panasonic GF1 improves on the color accuracy performance of its brand mate GH1, but still lags the competition overall.

The GF1 offers nine preset 'film modes,' each of which affects contrast, sharpness, saturation and noise reduction. Six of these presets are in color, as shown in the swatches below, taken from our test shots under studio lighting. There are also three black and white film modes, Standard, Dynamic and Smooth.

Including high-ISO noise reduction settings as part of color mode settings is a Panasonic peculiarity, and not one we favor. It would make much more sense to maintain a separate noise reduction control, as found on most SLRs. It would also be nice to be able to turn off noise reduction altogether, to maximize image detail, but this isn't allowed.

The contrast, sharpness, saturation and noise reduction settings for each preset can be adjusted along a five-step scale. These customized versions can then be stored in one of two My Film slots for future access.

The chart below shows same-size crops from test shots of the ColorChecker chart in each color mode. Dynamic and Vibrant modes were highly oversaturated to produce more dramatic results (112% and 123% respectively), while the Nostalgic mode damps down saturation to about 93.5% for a muted tone. The Nature setting tweaks blue and red reproduction but produces a pretty accurate green value, albeit 10% oversaturated.

White balance accuracy is a definite strength of the GF1: it outscored all the other cameras in our comparison group by a healthy margin. The automatic white balance system is the strong suit here, with extraordinarily accurate results under often-tricky fluorescent lighting, and very little of that orange tint that seems almost inevitable when shooting with auto white balance using standard household incandescent bulbs.

We test white balance both using the camera's automatic setting and by taking a custom white balance reading under three different lighting conditions. Consistent illumination for test purposes is provided by an X-Rite Judge II lightbox.

Automatic White Balance ()

The overall results here are exceptionally accurate, with minimal color shift even under difficult lighting conditions. The daylight test shots produced colors that were slightly cool, but it's very unlikely you'd notice the difference in an actual photograph. Incandescent lighting is the bane of every digital camera, consistently causing higher color error than other types of illumination. For the GF1, though, the shift toward warmer tones is barely noticeable. The automatic white balance system produced nearly flawless results under fluorescent lighting.

Custom White Balance ()

Taking a custom white balance reading essentially eliminated the already modest warm shift under incandescent lighting, and didn't really make much difference under fluorescent and daylight illumination, which were already pretty spot-on using the automatic white balance system.

The GF1 scored significantly better than the competition here. It's interesting to note that the E-P1 also showed better-than-average performance in our white balance testing.

It's a good thing that the automatic white balance system performed so well, because there are only five presets to use as a fallback. Strangely, this doesn't include a fluorescent option; we often see several fluorescent choices, to compensate for the variety of available bulbs.

The GF1 has two manual white balance slots, so readings can be saved for later use. Taking a reading is fast and easy, with clear on-screen prompts.

The white balance can be set directly in degrees Kelvin, ordinarily a pretty esoteric procedure, but useful here because the Live View display changes as you change the setting the preview the effect of your adjustments. Similarly, preset and custom white balance settings can be finely adjusted along the green-magenta and amber-blue axes, with a live on-screen preview.

White balance bracketing is also available, using the WB fine adjustment system to set the bracketing increments. Three versions of the shot are taken with a single press of the shutter.

In our long exposure test, which analyzes color accuracy and image noise over a range of shutter speeds, the GF1 again shows improvement over the GH1, but still comes up short compared to other cameras. We shoot the X-Rite ColorChecker chart under dim 20-lux illumination at shutter speeds ranging from 1 second to 30 seconds, with long exposure noise reduction on and off, then use Imatest software to determine the camera's performance. More on how we test long exposure.

Color error is high across the board, with the long exposure filter having little effect. Saturation wasn't bad, hovering around 100% before dipping significantly at the two longest exposure settings, but the color values are off throughout.

Image noise is quite high too and, as we sometimes see, the long exposure noise reduction system makes matters slightly worse. Long exposure noise reduction works by taking a second exposure with the shutter closed, then digitally removing the noise that appears in that second exposure from the image. Problem is, image noise is inherently random, so this approach is hit-and-miss at best.

The GF1 produced better results than the GH1, but comes up short compared to the Olympus E-P1, which also relies on a small Micro Four Thirds sensor, and substantially behind the Canon and Nikon with their APS-C format sensors.

Image noise starts at a high level (around 1%) even at ISO 100, and nearly 1.5% with noise reduction at its lowest setting. Once you get past ISO 800 the noise levels render the images pretty much unusable unless you crank the noise reduction settings up all the way. The good news here, as shown in our sample photos, is that the noise reduction processing doesn't obliterate too much image detail.

Image noise in the blue channel is slightly elevated above the rest, bad news for clean reproduction of those lovely blue skies in your photos. More on how we test noise.

The GF1 offers settings from ISO 100-3200. If you prefer finer control, you can set ISO increments to 1/3 stop in the recording menu.

There are two flavors of automatic ISO adjustment, the standard Auto ISO based on light level and an additional Intelligent ISO system that factors in subject movement to boost ISO and shutter speed when called for. In either case, the user can set an upper ISO limit to prevent excessive image noise.

The following same-size crops are taken from photos of our standard still life, taken in aperture-priority mode with automatic white balance.

Dynamic range test results for the GF1 were slightly better than the Olympus E-P1, but neither camera excelled here. A wide dynamic range means you can take photos in high-contrast situations and maintain detail both in the very bright and very dark areas. The good news here is that the GF1 dynamic range doesn't become severely impaired until you get past ISO 800. However, it starts out low even at the least demanding ISO settings.

To test dynamic range we photograph a Kodak stepchart across the full range of aperture settings, at each available ISO, and use Imatest software to analyze the resulting images. More on how we test dynamic range.

When set to ISO 200, both the GF1 and the E-P1 fared poorly here, but it's interesting that the equally Micro Four Thirds Panasonic GH1 nearly matched the Nikon and Canon results.

Here are the comparative results for the cameras in our test group, again demonstrating that while sensor size is a factor, it's not definitively linked to dynamic range performance, with the Canon T1i turning in mediocre numbers and the GH1 scoring very well here..

Autofocus performance has been a key strength of the Lumix G series from the start, and this continues with the GF1. The Live View autofocus on most digital SLRs is too slow to be practical when shooting moving subjects. Panasonic, though, has figured out how to make contrast detect autofocus nearly as fast as the standard SLR phase detect system, and certainly workable for all but the most sports-oriented photography. This is an area where the GF1 has a clear advantage over the Olympus E-P1, which suffers from pokey autofocus speeds.

The continuous autofocus in video mode pioneered on the GH1 is also implemented on the GF1, though without the single 10x lens super-quiet the company provides as the GH1 kit lens, you may pick up some focusing noise while shooting in continuos autofocus mode.

The autofocus system supports four modes: 23 Area, Single Area, Face Detection, and AF Tracking.

It is also possible to select between AF-S (autofocus single) and AF-C (continuous) modes. AF-S focuses when you press the shutter halfway and maintains that setting, even if you move the camera. AF-C keeps refocusing as necessary while you hold the shutter down, even if your subject moves, or you move the camera. Yet another set of autofocus options are prefocus settings, available through the custom settings menu. Here you can choose from Q-AF (Quick Autofocus), which tries to autofocus whenever the camera is held still, and C-AF (Continuous Autofocus), which attempts to maintain focus at all times, even if the camera is moving and your finger is nowhere near the shutter button, with compatible lenses. Confusing terminology rules here (having both Autofocus Continuous and Continuous Autofocus as distinct choices isn't playing fair), but you do get a lot of flexibility to handle different shooting situations. Of course, using the prefocus modes is going to result in a significant battery life hit.

There's a bright red autofocus assist lamp on the front left, right below the LUMIX logo, which does a nice job when the lights are low. However, the positioning isn't perfect. It's very easy to cover up the lamp with your right middle finger while shooting, especially if you have large hands.

Panasonic continues with its odd variant to face detection, which it calls face recognition. You can register up to six faces in the camera's built-in memory, complete with name, birthday and a priority rating if you choose. Then, when the feature is turned on during shooting, those registered faces will be given preferential treatment when focusing and setting exposure. The name can even be displayed on screen, for no apparent reason. The face recognition concept does have some interesting benefits, though. When taking group photos (at a school concert, for example), it will help make sure your little darling is in focus rather than some random kid. And during playback, it's possible to view only images which include recognized faces.

In our long exposure test, which analyzes color accuracy and image noise over a range of shutter speeds, the GF1 again shows improvement over the GH1, but still comes up short compared to other cameras. We shoot the X-Rite ColorChecker chart under dim 20-lux illumination at shutter speeds ranging from 1 second to 30 seconds, with long exposure noise reduction on and off, then use Imatest software to determine the camera's performance.

Low light sensitivity is not one of the Panasonic GF1's strengths. The camera needed 25 lux of light to reach 50 IRE on our waveform monitor when we shot using its 30p frame rate (MJPEG compression), and it required 29 lux of light to reach the same levels when shooting at 60p (AVCHD Lite compression). These numbers aren't that much worse than what we've seen from other video-DSLRs, but they are worse nonetheless.

The image analysis software found a bit of color fringing when shooting at the widest lens setting, but it's inconsequential when viewed with the naked eye.

The test images shot at the widest 14mm setting (equivalent to 28mm on a 35mm camera) are tack sharp with the lens wide open and still very good even at f/22. There's no appreciable chromatic aberration to be found.

At the halfway point in the focal length range the results are very close to the shots from 14mm.

Close inspection reveals a bit more softness at the narrowest setting, particularly with the lens stopped own all the way, but it's still a praiseworthy performance.

We found very low distortion when shooting at the full telephoto distance, and only 0.8 percent at the widest setting and the middle of the focal range.

The Panasonic GF1 records with two different frame rates depending on what compression system you use. Using the MJPEG compression the camcorder records 30p footage. With AVCHD Lite the camcorder records at 60p, although the sensor output is still 30 frames per second. When we imported the GF1's AVCHD Lite footage using Final Cut Express and iMovie we found the program having difficulty dealing with the 60p frame rate. The footage played back at double speed and looked sped-up. We attributed this problem to an incompatibility with the AVCHD Lite codec. When we viewed the footage on a television, however, it played perfectly fine (at the correct speed). Panasonic recommends using the MJPEG option when you plan on importing the video onto a computer, and using the AVCHD Lite when you plan on viewing your clips on an HDTV. More on how CamcorderInfo tests motion.

With the GF1, we noticed some artifacting and pixelation on the RGB pinwheel in our test footage, although it wasn't that bad. It was similar to what we saw on the Nikon D5000's test footage. The GF1 rendered choppy motion at times, but objects moved fluidly in most of our test footage.

The Olympus E-P1's motion test video had slightly less artifacting than the Panasonic GF1, but it also rendered a smoother image. Like the GF1, the E-P1 also tops out with a 1280 x 720 resolution and it uses the MJPEG codec to capture video. The Olympus does not have an AVCHD or AVCHD Lite recording option and all its videos record at a 30p frame rate.

The Panasonic GH1 is probably the best video-capable DSLR we've seen when it comes to motion. It can capture Full HD video (1920 x 1080) with a 24p frame rate, or you can record 1280 x 720 video at 30p and 60p. The GH1's Full HD mode did render some choppy motion, but the lower-resolution options captured smoother videos with less blur. The camera has a lot of options when it comes to frame rates, which makes it one of the most versatile video-DSLRs on the market.

The Nikon D5000 had a lot of problems capturing motion videos. First of all, the camera produced a terrible rolling shutter effect, which is something we've seen from all video-DSLRs that don't use the Micro Four Thirds format. This rolling shutter added a significant amount of wobble whenever we panned or quickly moved the camera. Secondly, the Nikon D5000 had a lot of artifacting in our test video, and it rendered jagged lines on our black and white rotating pinwheel. The Nikon D5000 records 24p video at 1280 x 720 using the MJPEG compression.

The Panasonic GF1 did alright in our sharpness test, but its numbers weren't as high as other cameras that record 720p video. The GF1 managed a horizontal and vertical sharpness of 575 lw/ph in our testing. These are slightly lower numbers than what the Olympus E-P1 and Nikon D5000 were capable of (both record 720p video). The Panasonic GH1 was obviously the leader here because it can capture video at a 1920 x 1080 resolution. When testing the GF1 we did not notice any difference in sharpness whether we used the camera's MJPEG or AVCHD Lite shooting mode. More on how CamcorderInfo tests video sharpness.

Low light sensitivity is not one of the Panasonic GF1's strengths. The camera needed 25 lux of light to reach 50 IRE on our waveform monitor when we shot using its 30p frame rate (MJPEG compression), and it required 29 lux of light to reach the same levels when shooting at 60p (AVCHD Lite compression). These numbers aren't that much worse than what we've seen from other video-DSLRs, but they are worse nonetheless.

In the past, we've had complaints about some of the G-series camera controls. Specifically, the single control dial can be clicked for direct access to exposure compensation settings. On the G1, we frequently clicked this control accidentally, leading to lots of poorly exposed shots. On the GH1, the dial click was made stiffer, lessening the problem. This time out, Panasonic has solved the problem entirely.

Our other problem was the movie record button the GH1, which was for all practical purposes part of the thumb rest and just aching to be pushed by mistake. This time out the control has been moved to the top of the camera, out of harm's way without sacrificing instant access convenience.

The GF1 offers nine preset film modes, six in color and three in black and white. For color, these include Standard, Dynamic, Nature, Smooth, Nostalgic and Vibrant; for black and white there are standard, dynamic and smooth. We have samples of the same scene shot in each of these modes in the Sample Photos section, in the Film Mode Examples.

Each color preset mode can be adjusted for contrast, sharpness, saturation and noise reduction, with five steps for each setting. The black and white modes work the same way, except there is no saturation control. Having noise reduction as a film mode setting rather than an overall camera setting is an odd choice, making changes less convenient than the more typical procedure. You're also prevented from turning off noise reduction completely, as we often do when trying to tease out as much image detail as possible. Considering the fact that the GF1 uses a Micro Four Thirds sensor, which are typically noisier than the common digital SLR APS-C format sensor, it's understandable that the company would encourage users to use noise processing, but it shouldn't be a requirement. At the same time, we have to admit that the algorithm used by Panasonic produced far less detail loss than we expected.

Multi Film bracketing is an interesting feature that lets you select two or three different Film Mode settings and take shots in each one consecutively. Unlike white balance bracketing, you don't take a single shot and have it saved in different versions: in this case, you'd have to press the shutter repeatedly or set the camera to burst mode.

My Color mode, a newbie-friendly feature found on the G1 and GH1 has been improved with the GF1. In the earlier version, the user gets to set color, brightness and saturation, each along an eleven-step scale, with the results previewed interactively on screen (as you'd imagine, this substitutes for Film Mode settings). These options are still available by choosing Custom when the mode dial is set to My Color, but there are also seven presets that work much like the artsy filters found on Olympus and Pentax cameras. The My Color settings can be applied to still or video shooting.

The GF1 offers direct access to several key shooting controls, including ISO, white balance and focus mode, via buttons on the back of the camera. Most of the other frequently changed settings in record mode, including film mode, image size and flash control, are a single button-press away, via the Quick Menu system (which has its own dedicated button). The Quick Menu system makes the information overlay on the Live View screen interactive, navigable with the control dial or four-way controller. To change a setting, you press the Menu/Set button.

For the remaining settings, there's a typical multipart menu system. The menus are easy enough to read, color coded for quick identification, and settings include both icons and legible text, so you're never stuck guessing what a line item controls. However, each menu can run up to five screens deep, meaning a lot of scrolling and searching before you find what you're after.

The 204-page Operating Instructions manual isn't bad, but it has its peculiarities. For example, before even telling you how to hold the camera or take your first picture, there's a detailed presentation of every obscure option in the setup menu. And don't go looking for 'video' or 'movie' in the index -- that's 'motion picture' to you. On the plus side, there are plenty of illustrations, the scene mode settings are explained (which is often skipped in user manuals) and while the writing and presentation can get a bit dense at times, all the information you need to use the multitude of camera features is in here somewhere. To see for yourself, you can download a pdf file copy of the manual here.

It's a pleasure to shoot with the GF1, and a pleasure to carry it along too. With the 20mm pancake lens attached, the camera will fit easily into a jacket pocket or purse. And even with the 14-45mm kit lens, you won't eat up much space in a shoulder bag or backpack when traveling with the GF1. With the pancake lens attached, the whole package weighs in at just under a pound (15.6 oz. / 442g), and even with the zoom it's still a lightweight18.9 oz. (537g). By way of comparison, the GF1 body is 25% lighter than the Olympus E-420, the smallest digital SLR on the market.

Fortunately, the compact size presents only one significant handling problem. The right front has a rounded, slightly raised grip with a silver insert providing a little extra traction. We would have made this grip a bit deeper, but it's fine the way it is. There's a nice curved thumb rest on the back, with a substantial top ridge that effectively keeps your thumb from drifting over to the control dial mounted above it. Our only concern is the location of the autofocus assist lamp, on the front of the camera, below the LUMIX logo. We frequently found our middle finger completely or partially covering this lamp; it takes a concentrated effort to avoid it, which is one more thing to think about when shooting in low light.

The camera construction feels solid, the buttons have a pleasing clickiness, the dials move with precision. There's a dedicated movie record button on the far right on the top, available for instantly taking advantage of video shooting opportunities without having to spend time turning the mode dial. This button was located on the back of the GH1, easy to press accidentally. We had no such problem with the new top-mounted position. Another problem with previous Lumix Micro Four Thirds cameras, an overly sensitive control dial that's easy to click and turn accidentally (changing the exposure compensation settings in the process) was improved in the move from the G1 to the GH1, and really eradicated with the GF1.

The LCD screen is a 3-inch 460,000-dot display that looks particularly sharp when reviewing your shots. It looks fine when shooting in well lit areas, but when the light gets low, the refresh rate gets slow, leading to stuttering and even some blurring as you pan.

The LCD screen (along with the optional electronic viewfinder) can be adjusted to one of seven brightness levels. In addition, there are two optional modes for adjusting screen brightness to fit the shooting environment: Auto Power LCD reacts to detected light levels, while Power LCD turns brightness to full blast, useful when shooting outdoors.

LCD color saturation and color reproduction (along a yellow-magenta axis) also offer seven settings.

Secondary Display

The monochrome LCD found on higher-end traditional SLRs to display camera settings when viewed from above is a rarity even on most consumer SLRs, and absent as expected on this slender Micro Four Thirds model.

The mono LCD display is small and disappointing.

The GF1 doesn't come with a viewfinder, but it is compatible with a slick optional electronic viewfinder, priced at $200. The DMW-LVF1 attaches to the hot shoe (a plug slips into a dedicated electronic connection on the back of the camera) and recreates the Live View display in miniature. The viewfinder can also be set at an angle (up to 90 degrees), a benefit of its unusual mounting. This contrasts with the Olympus E-P1, which offers only an optical viewfinder accessory, priced at $100, that displays the scene as it would be seen through the 17mm pancake lens.

Overall, the GF1 image stabilization system, using the kit zoom lens, was unimpressive. It produced marginal improvements at slow shutter speeds with high camera shake, but doesn't measure up to the tested performance of other cameras, including its brand mate GH1.

To test image stabilization, we mount the camera in a custom-designed computer-controlled rig that produces controlled movement patterns. We run separate horizontal and vertical movement tests, each at both a high and low camera shake setting. By comparing the resolution of test images taken with the image stabilization system turned on with those taken with image stabilization off, we can determine the system's effectiveness at reducing blur.

While available shooting modes largely the same as the Lumix G1 and GH1, the GF1 does improve and expand the implementation of the Custom Settings capability. Users can register up to four different combinations of settings by storing the current camera status is one of four available slots (up from three slots in previous models). While the G1 and GH1 had only a single mode dial position for accessing these custom settings (you had to decide beforehand, via the menu system, which stored profile would be assigned to this position). The GF1 provides two mode dial spots, one always pegged to the first custom settings profile, the second selectable from the remaining three options.

The movie controls have also changed from the GH1, which provides full control over shutter speed and aperture settings in Creative Motion Picture mode. The GF1 offers Motion Picture Program mode instead, which provides manual aperture setting for depth of field control plus exposure compensation.

Autofocus performance has been a key strength of the Lumix G series from the start, and this continues with the GF1. The Live View autofocus on most digital SLRs is too slow to be practical when shooting moving subjects. Panasonic, though, has figured out how to make contrast detect autofocus nearly as fast as the standard SLR phase detect system, and certainly workable for all but the most sports-oriented photography. This is an area where the GF1 has a clear advantage over the Olympus E-P1, which suffers from pokey autofocus speeds.

The continuous autofocus in video mode pioneered on the GH1 is also implemented on the GF1, though without the single 10x lens super-quiet the company provides as the GH1 kit lens, you may pick up some focusing noise while shooting in continuos autofocus mode.

The autofocus system supports four modes: 23 Area, Single Area, Face Detection, and AF Tracking.

It is also possible to select between AF-S (autofocus single) and AF-C (continuous) modes. AF-S focuses when you press the shutter halfway and maintains that setting, even if you move the camera. AF-C keeps refocusing as necessary while you hold the shutter down, even if your subject moves, or you move the camera. Yet another set of autofocus options are prefocus settings, available through the custom settings menu. Here you can choose from Q-AF (Quick Autofocus), which tries to autofocus whenever the camera is held still, and C-AF (Continuous Autofocus), which attempts to maintain focus at all times, even if the camera is moving and your finger is nowhere near the shutter button, with compatible lenses. Confusing terminology rules here (having both Autofocus Continuous and Continuous Autofocus as distinct choices isn't playing fair), but you do get a lot of flexibility to handle different shooting situations. Of course, using the prefocus modes is going to result in a significant battery life hit.

There's a bright red autofocus assist lamp on the front left, right below the LUMIX logo, which does a nice job when the lights are low. However, the positioning isn't perfect. It's very easy to cover up the lamp with your right middle finger while shooting, especially if you have large hands.

Panasonic continues with its odd variant to face detection, which it calls face recognition. You can register up to six faces in the camera's built-in memory, complete with name, birthday and a priority rating if you choose. Then, when the feature is turned on during shooting, those registered faces will be given preferential treatment when focusing and setting exposure. The name can even be displayed on screen, for no apparent reason. The face recognition concept does have some interesting benefits, though. When taking group photos (at a school concert, for example), it will help make sure your little darling is in focus rather than some random kid. And during playback, it's possible to view only images which include recognized faces.

And, of course, there's manual focus mode, chosen via an on-screen menu selection rather than a control on the lens. By default, a zoomed-in view of the scene (up to 10x magnification) appears when you start focusing manually, returning to normal view when you depress the shutter button halfway. In certain circumstances (when shooting on a tripod, for example) we found this useful, though having the rest of the screen disappear while trying to manually focus on a moving subject is less practical. You can also set the camera to allow fine manual focus adjustment after the autofocus system has done its business.

The options here are generous, with four aspect ratio options, and three resolution settings for each.

There are two compression settings for JPEG images, fine and standard. Shooting RAW files is also supported, either on their own or with an attached fine or standard JPEG image.

Audio Recording

The mic can be used to record 5 seconds of audio along with a photo. This is a useful feature when you want to make a note about the shooting situation without fumbling for a pen and paper. Audio annotations can also be added during image playback.

The GF1 supports two burst mode settings: High at 3 frames per second and Low at 2 frames per second. When the camera is set to AFC mode, the camera will adjust focus between shots, cutting the burst rate.

Panasonic promises a top burst rate of 3 shots per second. Our lab tests surpassed these expectations, delivering a solid 3.3 shot per second performance, making it a respectable contender within the consumer SLR market.

In addition to the basic 10-second and 2-second shutter delay options, you can also choose to have three consecutive shots taken after a 10-second delay, handy if you're racing to get into the photo.

The GF1 offers nine preset film modes, six in color and three in black and white. For color, these include Standard, Dynamic, Nature, Smooth, Nostalgic and Vibrant; for black and white there are standard, dynamic and smooth. We have samples of the same scene shot in each of these modes in the Sample Photos section, in the Film Mode Examples.

Each color preset mode can be adjusted for contrast, sharpness, saturation and noise reduction, with five steps for each setting. The black and white modes work the same way, except there is no saturation control. Having noise reduction as a film mode setting rather than an overall camera setting is an odd choice, making changes less convenient than the more typical procedure. You're also prevented from turning off noise reduction completely, as we often do when trying to tease out as much image detail as possible. Considering the fact that the GF1 uses a Micro Four Thirds sensor, which are typically noisier than the common digital SLR APS-C format sensor, it's understandable that the company would encourage users to use noise processing, but it shouldn't be a requirement. At the same time, we have to admit that the algorithm used by Panasonic produced far less detail loss than we expected.

Multi Film bracketing is an interesting feature that lets you select two or three different Film Mode settings and take shots in each one consecutively. Unlike white balance bracketing, you don't take a single shot and have it saved in different versions: in this case, you'd have to press the shutter repeatedly or set the camera to burst mode.

My Color mode, a newbie-friendly feature found on the G1 and GH1 has been improved with the GF1. In the earlier version, the user gets to set color, brightness and saturation, each along an eleven-step scale, with the results previewed interactively on screen (as you'd imagine, this substitutes for Film Mode settings). These options are still available by choosing Custom when the mode dial is set to My Color, but there are also seven presets that work much like the artsy filters found on Olympus and Pentax cameras. The My Color settings can be applied to still or video shooting.

The Panasonic GF1 offers two compression options for video: Motion JPEG (MJPEG) and AVCHD Lite. MJPEG compression is commonly found in digital cameras and it is popular on video-capable DSLRs as well. The codec has been around for a while and it is compatible with most media players and editing programs. For these reasons, Panasonic recommends you shoot MJPEG if you plan on working with or viewing your footage on a computer.

The AVCHD Lite compression is an off-shoot of AVCHD, which is used on nearly all consumer HD camcorders that don't record to tape. In theory, there isn't much of a difference between AVCHD and AVCHD Lite—the 'Lite' variety simply tops out with a 1280 x 720 resolution. Interestingly, however, we noticed a number of editing programs having difficulty dealing with footage shot using the AVCHD Lite compression on the GF1. Final Cut Express imported the AVCHD Lite footage with no problem, but the clips ran at double speed when we played them on a computer. The same thing happened when we imported the footage using iMovie and Adobe Premiere. Since AVCHD Lite is so new, it seems many editing programs have yet to provide plug-ins or updates to handle the compression system. According to Apple, the newest version of iMovie HD should work with AVCHD Lite.

The GF1 records video at a maximum resolution of 1280 x 720 (available in both MJPEG or AVCHD Lite). The MJPEG option records video with a 30p frame rate, while AVCHD Lite uses a 60p frame rate (the sensor output is 30 frames per second, however). This 60p frame rate with a 30p sensor output is probably the main reason certain editing programs had difficulty playing back the footage at the correct speed. Strangely, the Panasonic GH1 had the same setup for its 60p mode—and we had no trouble dealing with the footage captured by that camcorder.

The Panasonic GF1 has numerous quality and resolution options for recording video. The table below lists all the available recording options: Find out how the performed in our video image quality test./r:link_to_content

When shooting video with the Panasonic GF1 most of the camera's controls run automatically. ISO and shutter speed can never be set manual for videos, but the camera does allow for limited aperture and exposure adjustment. You can shoot video with the GF1 in any mode, including scene modes and Intelligent Auto (iA) mode.

If you want to control aperture in your videos you can only do so in Motion Picture P mode on the GF1. In this mode you can control exposure and something Panasonic calls 'peripheral defocus,' which is essentially aperture control, but with a different name.

Auto Controls

Intelligent Auto mode enables the GF1 to automatically select a scene mode it feels is applicable to your shooting situation. In video mode the GF1 will either set itself to i-Portrait, i-Scenery, i-Low Light, i-Macro, or a standard setting if none of the scene modes apply. We didn't find this intelligent scene selection to be all that useful in video mode. More often than not it worked better to just select a scene mode ourselves.

When shooting video in Program mode (P), Aperture-priority (A), Shutter-priority (S), or Manual mode (M), the camera will automatically set aperture and shutter speed (you can adjust exposure, however). It doesn't matter what you set the shutter or aperture to in these modes—once you press the video record button the camcorder will automatically select its own settings.

Auto exposure worked quite well on the GF1 and we found it to transition nicely from different light sources. The camera has a couple of different autofocus options, which we discuss in more detail in the Focus section below.

Zoom

The kit lens for the GF1 is a 14-45mm f/3.5 - f/5.6 Micro Four Thirds lens. The kit lens doesn't provide the longest zoom (roughly a 3x optical zoom), particularly when compared to traditional HD camcorders (usually 10x - 16x optical zoom). Zooming is performed by rotating the zoom ring on the lens—and yes, the camera's built-in speaker picks up plenty of noise associated with adjusting the zoom lens.

The GF1 also has a 2x and 4x digital zoom option that can be used in video mode.

Focus

The GF1 does have a live, continuous autofocus in video mode, but it is much slower than a regular camcorder. Subjects often took 4-5 seconds to come into focus and the transition was gradual and smooth. Some may like the slow transitional focus performed by the GF1, as it offers a very different aesthetic to the quick, snap-like focus found on many consumer camcorders.

You can also set focus by pressing the shutter button down halfway, just as you would when shooting photos. Manual focus is adjusted by rotating the focus ring on the camera's lens. Unfortunately, you cannot adjust focus manually in video mode unless the camera is set to manual focus only. There is no option for simultaneous auto/manual focus when shooting video—you must choose one or the other.

Exposure Controls

Exposure can be adjusted in most modes and you can even adjust the levels during recording. Exposure is set by rotating the small dial on the back side of the camcorder (in the upper right).

Aperture can be manually set on the GF1, but it is called peripheral defocus and you can only adjust the setting in Motion Picture P mode. You set the peripheral defocus by rotating the same dial that is used to adjust exposure. The camera allows you to switch between exposure and aperture adjustment by pushing in on the dial.

Our main problem with the peripheral defocus option is that the camera doesn't tell you what f-stop values you are actually setting the camera to. Instead, a bar-display appears on the LCD with one end showing a blurred background with an in-focus foreground and the other end showing both the foreground and background in focus. With this, you adjust the peripheral defocus to produce the desired depth of field effect. This system may be easier for beginners to understand, but pros will definitely be perturbed by the fact that there is no numeric display of f-stop values in video mode.

Other Controls

Since the GF1 doesn't offer shutter speed or ISO controls in video mode the only other manual controls worth talking about are the camera's color modes. The GF1's color modes work in video mode just like they do for still photos. You can choose one of the pre-set options or you can make your own custom color setting.

The GF1 also has a flicker reduction setting that is meant to reduce flicker caused by fluorescent lighting in some areas. With flicker reduction turned on the shutter speed is locked at 1/100 of a second and peripheral defocus cannot be adjusted.

The Panasonic GF1 doesn't have much in the way of audio features. The GF1's built-in mic is tiny, located on the top of the camera, and only records monaural audio. You can also expect the mic to pick up noises associated with the camera's functions—rotating dials, focus/zoom motors, etc. Simply put, don't expect to be able to record quality audio with the Panasonic GF1.

The camera does have one audio feature, Wind Cut, that attempts to reduce noise associated with rustling wind. There are some video-capable DSLRs that offer built-in stereo microphones, as well as a few that have external microphone inputs.
