On the wallet-friendly side of the spectrum is the Olympus PEN E-PM2 (MSRP $499.99 with lens). The naming scheme might make this camera sound like a sequel, but it's so much more than that. Where most entry-level mirrorless cameras come with older image sensors, the E-PM2 has been given the same great praiseworthy sensor as the more expensive E-P5 and OM-D E-M5.
The Olympus PEN E-PM2 is a perfect exercise in the benefits of economies of scale. As one of the smaller camera manufacturers, Olympus often has to source camera components from other companies. In this case, Olympus has borrowed for the E-PM2 is the Sony-manufactured sensor that is also found in the Olympus OM-D E-M5. While this certainly saves cost for Olympus, it also saves cost for the consumer; with practically identical image quality to arguably the best compact system camera on the market, the E-PM2 represents a great value for novice shooters who want great images but aren’t ready for all that the OM-D has to offer.

As you’d expect given the shared equipment, the E-PM2 performed as well in our lab tests as the rest of Olympus’ lineup. We should note that there are some minor tweaks—notably tuned up noise reduction and an insane amount of default oversharpening—though these only appear when shooting JPEGs as opposed to RAW photos.


The Olympus E-PM2 managed a very nice score in our color accuracy test, with a saturation-corrected color error of just ∆2.27 in the Muted color mode. The “muted” mode also resulted in near-perfect saturation. While the mode’s name may suggest an intentional flattening of colors, they’re merely realistic compared to the other modes on offer; Every other color mode bumped saturation up by at least 5%, resulting in more vivid photos that are slightly less accurate.

Compact, lightweight and inviting. 

With each generation of the E-PM series, Olympus has managed to shrink the footprint of the camera while preserving the distinctive retro look and solid build quality of the more expensive PEN models. Small though it may be, the E-PM2 is just as easy to shoot with as the slightly bigger, more expensive E-PL5

Of course, the slimming of size and price means that there are features left out. Even though this PEN has an adequate 3-inch capacitive touchscreen, it lacks any tilting mechanism—useful when shooting with the camera above your head or from the hip. The E-PM2 also goes without a mode dial and some other, less important buttons. If a tilting touchscreen or a dedicated mode dial sound appealing, then plan on plonking down the extra $100 or so for the E-PL5.  

Although the first PEN Mini was a fetching camera with a stylish brushed metal finish, its smooth exterior handled like a wet bar of soap. Thankfully, the E-PM2 is blessed with a new front grip. It might not look like much, but the grip provides more than enough purchase for such a lightweight body.

Our one reservation about the E-PM2's design is the lack of a mode dial. For experienced photographers used to quickly switching modes quickly, that’s where this camera falls short. All our fears were for naught. The E-PM2 makes it easy to change modes via the menu system, with a mode selection screen that is pulled up with a press of the Menu button. We actually preferred the lack of mode dial to the loose mode dial we found on the E-PL5.  

The E-PM2 is just about as fully-featured as its brethren.

 
Even though this PEN's "Mini" designation calls it out as the baby of the bunch, the smaller size and price tag still net you a whole lot of camera.

The Super Control Panel obviates unnecessary, frustrating trips into the E-PM2's menu dungeon.

Of course, if you’ve never used an Olympus before, we have a word of warning: even though the E-PM2 offers great features that will definitely appeal to point-and-shoot users, the underlying menu system can be really daunting. If you stick with it, you’ll get used to it eventually. The best advice we can give you is to turn on the Super Control Panel (Google it for instructions). The SCP will obviate unnecessary, frustrating trips into the menu dungeon. 

Complex menus aside, Olympus has made satisfactory concessions for the less experienced photographers out there. To the right of the shutter button, there’s a button for Live Guide options— a list of settings meant to put more intimidating sounding features into plain English. Shutter speed control is labelled ‘Express Motions’ and aperture control boiled down to ‘Blur Background’. These options, along with an ample supply of Scene Modes, mean that even average Joes can take advantage of what the E-PM2 has to offer. 

Shooters both seasoned and amateur alike should know that Olympus is a bit behind the curve with WiFi integration. The E-PM2 just has EyeFi card compatibility, and nothing more. While we expect mobile device connectivity to become a standard feature in the future (and, knowing Olympus, the implementation will probably be a refined version of what we saw in the E-P5), it’s a weak spot for the PEN cameras when compared to Panasonic’s more recent offerings. 

While you don’t get the nifty photo collage mode of the E-P5, the E-PM2 still has a halfway decent set of art filters to choose from. Of course, you could always choose to use an adapter and real vintage lenses to achieve a retro effect. But, if you need autofocus and zoom, the Grainy Film and Pin Hole filters are decent enough facsimiles. If you have problems choosing what look you like, there’s an excellent Art Bracket feature that produces 12 copies—one for each art filter—for each shot you take. 

The Olympus E-PM2 performed admirably in our noise tests, with an effective combination of a well-rounded image sensor and a noise reduction system that was potent and yet delicate with fine detail.

In terms of raw noise percentages, the E-PM2 produced an average of 1.19% of noise at base ISO (ISO 200) with noise reduction turned to the “off” setting. That number rose steadily from there, hitting 1.46% at ISO 400, 1.71% at ISO 800, and crossing the 2% threshold slightly at ISO 1600.

If you bump noise reduction up to the Standard setting noise begins at just 0.8%, rising steadily still, but only hitting 1.31% at ISO 1600, 1.5% at ISO 3200, 1.85% at ISO 6400, and well above from there. Standard is the default setting for the camera when shooting JPEGs, and unless you want to develop RAW shots later we suggest keeping it there. As you can see in our still life crops below, noise is kept in check and fine detail still remains through ISO 3200.

The sensor tops out at a max ISO speed of 25600, though even with noise reduction turned all the way to the High setting, noise remained at 2.73%. ISO speeds 6400-25600 should only be used when there is no other alternative.
Considered the true test of an image sensor’s capabilities, dynamic range is merely the number of different light levels that a camera can capture in a scene with a single image. We test this aspect of performance using the Xyla 21, which has 21 patches, each half as bright as the one before it. The result is 21 total stops of range in a single scene, well beyond the capabilities of any current digital camera.

The E-PM2’s sensor does well here, considering its small size. The larger a sensor, the more room it has to gather light, which allows for a greater range of tonal values. The E-PM2 managed to capture around 12.2 stops of dynamic range at base ISO. The high amount of noise from the sensor does limit how useful some of this range is—if you try and pull up detail in the shadows, you often pull noise with it—but it’s a solid score and easily keeps the E-PM2 competitive with other entry-level DSLRs and mirrorless caneras.

More of the same from a tried-and-true sensor.

With the same sensor as the Olympus OM-D E-M5, the E-PM2 performed as well as expected. Olympus has a reputation for tuning color in order to achieve pleasing results. We measured some differences between the clinical ideal and even the E-PM2's most accurate mode, muted. Auto white balance performance was better-than-expected and custom white balance was about as good as the other Olympus offerings. Check out the sample photos below for examples of some of the punchy colors that Olympus is known for.

Video remains a weak spot for Olympus, even though the E-PM2 shoots 1080/30p footage by default. We noticed that clips looked grainy and soft—not two adjectives you want to hear describing Full-HD video. You shouldn't expect excellent quality results from the E-PM2, and if video is very important to you, you'll want to take a look at one of the Panasonic Micro Four Thirds offerings instead.

Shot-to-shot speed, on the other hand, is a strength of the E-PM2. At full resolution, you can shoot 8 frames per second in JPEG. The burst rate slows down after around 17 shots, but it's still among the stronger mirrorless performers out there today. The buffer fills more quickly if you're shooting RAW, and the larger files grind the camera to a halt as it finishes writing all those bits and bytes to the SD card.

We found that when we tested for still sharpness, the E-PM2 yielded different results than its siblings. Our numbers indicate a ton of oversharpening in JPEG with default settings in place, with as much as 30% applied in some instances. Most cameras apply extra sharpening when needed, but we found that the E-PM2's algorithms were way over the top. Thankfully, JPEG sharpening can be dialed down in the Super Control Panel, or you can shoot RAW.

One of the best introductory mirrorless options around. 

While some might gravitate towards the Sony NEX-3N for its larger APS-C-sized sensor, there’s no doubt that the E-PM2 is a solid performer. Micro Four Thirds makes an excellent system for beginners, with plenty of room to grow. Also, there’s the distinct benefit of being able to use the same lenses on Panasonic bodies, so you have a greater range of kit to choose from should you buy into the system whole-hog. 

Even for previous Olympus PEN owners out there, the E-PM2 would make for a nice upgrade from an older PEN due to its excellent sensor. You might yearn for the ergonomics of Panasonic’s GX7 or the weather sealing of the Olympus OM-D EM-5, but for many people, the E-PM2 is the Goldilocks of Micro Four Thirds. This camera’s pricing, size, weight, image quality, performance, features—all of them are just right. 

Where we found the noise reduction system to be delicate with fine detail, the camera’s attempts to improve sharpness could best be described as “ham-handed.”

When cameras are processing images, they very often will enhance sharpness around high-contrast edges by bumping up the brightness of the border. This improves a thing called acutance—the perception of sharpness—but when pushed too far it results in an ugly halo effect.

The E-PM2’s default sharpening level oversharpens by approximately 30% in most areas of the frame, occasionally pushing this to an absurd 50%. Essentially, what should be a dark gray box on a light gray background becomes a dark gray box with a pure white line around it. This does enhance sharpness when viewed on a screen or with very small prints, but your eyes will easily pick it up when you print a large image. As you can see below, the effect looks quite unnatural.
The E-PM2 performed excellently in our white balance tests, with some of the best results we’ve seen recently. Most notably, the camera even did well when shooting under tungsten lighting, with a color temperature error of just over 1000 kelvins. Every camera’s auto white balance struggles here, though most have errors in excess of 2000 kelvins. That was also the only lighting condition—for both auto and custom white balance—where the temperature error was over 100 kelvins.

Long story short: Just leave the E-PM2 in auto white balance and don’t worry about anything else.

The E-PM2 managed a very respectable 8 shots per second in our timing test, with focus locked on the first frame. This puts the camera in great company, and it’s significantly faster than most entry-level DSLRs and point-and-shoots.

Capacity is a little limited, however, as the E-PM2 was only able to capture around 16 JPEG images at full speed before slowing down to write the shots to the memory card. If you shoot RAW you can expect around 13 frames of capacity, though speed is nearly identical.
