There are no surprises in the autofocus system -- that is, the center-spot AF works well; the face-detection AF is frequently helpful and occasionally gets in the way (there needs to be an instantaneous override when you don't want to focus on the people); the full-time AF is easily confused and pulses too often when shooting video; and the tracking autofocus seems like it's working at the time but in actuality lags the subject. All of this is pretty much par for the course in today's AF systems, however.
Design and features
It has a modest-size body, but it's built along the same lines as the E-5 dSLR -- a bit tanklike, with a magnesium alloy body that's dust-and-weather sealed and weather resistant from -4F degrees to 140F degrees. While the PEN series eschews built-in electronic viewfinders (EVF), the OM-D takes advantages of that design's distinctive pyramid-shaped housing for the optical viewfinder's prism. Here it houses the EVF, along with a hot shoe and a connector for the bundled compact flash unit (the same connector used by the PEN models for the external microphone and other accessories). The viewfinder itself doesn't match that of the Sony Alpha NEX-7 -- it's smaller and because of the MFT 2x crop factor has a lower effective magnification -- but it's similar to the optional viewfinder for the PEN models and is still pretty nice.
Overall, I enjoy shooting with the E-M5. Like the NEX-7, it's a good size -- neither too large nor too small -- and comfortable to grip, and all the lenses are small enough to stash in a roomy jacket pocket if necessary. The retro look deservedly attracted quite a bit of attention, and several accidental drops attested to the camera's sturdy build.
The EVF and tilting OLED touch-screen display are bright and usable, though the latter becomes nearly invisible in direct sunlight and I always find OLEDs too cool and contrasty for my taste. The buttons feel mushy and some of them are a little too small for easy access (like the function and review buttons), and there's no way to lock the front dial, which adjusts exposure compensation -- with the inevitable consequences -- without changing its function entirely. And it's time for the company to overhaul its implementation of custom settings to bring it into parity with competitors to make them easier to use.

On the unique feature front is the ability to display and adjust the highlight and shadow areas of the tone curve in the viewfinder. It's a great idea, but a little difficult to use on the spur of the moment -- there's lots of pressing and fiddling with the tiny controls, and you're putting a lot of faith in the accuracy of the viewfinder. It would be a lot more convenient if you could save presets for immediate recall.
A little more useful is the ability to finely adjust a lot of parameters. For instance, you can program an exposure shift for each of the main three metering choices, set the maximum and minimum values for the histogram, choose which type of metering the auto exposure lock uses, and opt to keep a warmer tone in automatic white balance. You can customize the display in a gazillion different ways so that, for the most part, you only see the options you want. And while the camera doesn't have a full touch-screen interface, it is a touch screen and allows you to perform the operations you really want a touch screen for: touch focus with magnification, touch shutter and swiping navigation during playback. The one missing option is touch spot metering. Though it doesn't include built-in wireless as Samsung does, it's optional via the PenPal Bluetooth adapter. (For a complete accounting of the camera's features and operation, download the PDF manual.)
Furthermore, the relatively new 12-50mm lens is a really nice kit fit with this model. Though it's not as small as the typical 14-42mm version, it's got a load of nice features, including a macro setting and quiet electronic zoom for video, it's weather sealed and feels well built. It's a good focal range, too -- angle of view equivalent to 24-100mm. It's not the sharpest or fastest lens, and could probably use a better class of coatings, but that would also make it far more expensive.
You don't have a lot of choices if you're looking for something rugged under $1,000 that's better than most of the . There's the forthcoming Pentax K-30 dSLR, but it's bigger and clunkier. While you don't get best-in-class photo quality with the OM-D E-M5, it's a not-unreasonable trade-off for the rest of the package.
