Olympus OM-D E-M10 review: Olympus' E-M10 offers a good mirrorless alternative to a first dSLR
Though it doesn't deliver the best photo quality, the sum of the E-M10's design, performance and features add up to a nice upgrade from a point-and-shoot.
The E-M10 is a solid Micro Four Thirds camera that sits at the bottom of Olympus' higher end OM-D line; the line includes more advanced features, like an electronic viewfinder and tilting display, than the more compact PEN cameras. It's both designed and priced more for enthusiasts than the always-auto crowd, but with both a basic touchscreen interface and a physical-control-driven advanced interface, it's great if you want a camera you can grow into.
The Good
The Bad
The Bottom Line
Image quality
Overall, I'd classify the E-M10's image quality as good, not great; it looks typical of what I've seen from other Micro Four Thirds models with lower-end lenses, in this case, the new 14-42mm f3.5-5.6 power zoom lens. I also field tested with the new $399.99 25mm f1.8, which pairs well with the camera for things like portrait or street photography. In comparison, its big brother the E-M1 's shots look generally sharper, but we tested that with a better lens (the $999 12-40mm f2.8) because it's a higher-end camera. It uses the same sensor as the E-M5 but the newer image-processing engine of the E-M1; in general, the photo quality matches that of the E-M5.
As with all its cameras, Olympus hides the lowest-compression JPEG setting; you won't know it's there unless you actually read the manual. With the E-M1 I retested after discovering this; with the E-M10, I didn't. It compresses 4:1 at the default Fine setting, while the hidden Super Fine compresses at 2.7:1. If you want best quality, shoot raw.
The E-M10's JPEG shots in bright daylight look just a bit crunchy and over-processed, but at least at low ISO sensitivities the out-of-focus areas look nicely smooth and the kit lens delivers rounded out-of-focus highlights. At higher sensitivities, starting at about ISO 400, sharp areas look fine but areas that are even a touch out of focus start to get mushy and display noise-suppression artifacts. That's a concern if you plan to shoot sports, which frequently requires high shutter speeds and usually higher ISO sensitivities; while the camera might be able to keep up, there's little latitude if you don't get the focus spot-on. That said, in indoor lighting for still subjects at ISO 400 JPEGs look very good and you can probably even get away with ISO 800 and ISO 1600 in good light if you don't peer too closely at the details. You can gain back some detail by processing raw files starting in the middle ISO sensitivities, though clipped highlights frequently seem to be unrecoverable.

Like many cameras these days, Olympus offers two options for auto white balance, a normal mode and a mode that preserves some of the color of the light, generally to keep the warm tone of traditional light bulbs. I find the normal mode to be a lot cooler than I've seen with other cameras and that even under other lighting types I prefer the preserve warm tone setting better.
Video quality is fine for short vacation clips and other casual movies, but overall it's softer than I like. Diagonals don't look terribly jaggy and aliased at low ISO sensitivities, but by about ISO 1600 there's quite a bit of color noise.
Performance
When it comes to speed, I'd classify the E-M10 as sufficiently fast, and it's notably faster than the E-M5 . You'll be able to keep up with kids and pets, though you may miss some action shots. It's relatively slow to start up, about 1.3 seconds, in part because of the power zoom lens -- those always take more time to extend and initialize than a manual zoom or fixed focal-length version -- and partly because most mirrorless cameras take longer to initialize than comparable dSLRs.
Once powered on, it's reasonably fast compared to competitors. It takes about 0.2 second to focus and shoot in good light and about a tenth of a second longer in dim conditions; overall, the autofocus system works quickly and accurately. There's also a menu setting for decreasing release lag time, which sucks up more battery power but does shave about .07 second off the default settings. Time for two sequential shots, either raw or JPEG, runs about 0.4 second, which seems to be caused by the autofocus completely resetting even though the subject hasn't moved. With flash enabled, shot-to-shot time rises to about 1.3 seconds, which isn't bad.
Burst shooting with autofocus and autoexposure enabled runs 3.3fps, and it can sustain that rate for at least 30 frames, raw or JPEG. It even holds up fairly well when shooting raw+JPEG. In its high-speed burst, which fixes focus and exposure on the first frame -- that makes it useful in only a limited set of circumstances -- it sustains almost a 7fps burst for at least 30 JPEGs, about 7.4fps in raw, but for only 15 shots.
It's important that the camera has an electronic viewfinder -- and a good one -- because the LCD display gets pretty reflective in bright sunlight. Otherwise it's a bright display and responsive touchscreen. Although the battery life is only rated for about 320 shots, it seems to last longer.
Design and features
I enjoy shooting with the E-M10; it's pretty compact, especially equipped with the relatively flat 14-42mm power zoom lens. The tiny lenses are the real advantage of getting a Micro Four Thirds body over an APS-C model, even a mirrorless. Though the camera has a touchscreen you don't have to use it, and camera operation can be as automatic or manual as you like without losing the streamlined shooting feel. You can opt for Olympus' ingenious two-part ergonomic grip accessory (i.e., it's not a battery grip or vertical grip, just a bigger grip) does let you snap off a section for quick access to the battery/SD card) if you agree with me that the built-in grip feels a little shallow .
The top of the camera can look a little cluttered and intimidating, but the inclusion of front and back dials really helps when shooting anything but full auto. The mode dial includes the usual manual, semimanual and automatic modes plus a movie mode that adds some manual controls, Olympus' Photo Story mode (which automatically collages selected photos), and its Art Filter mode. That latter remains one of the better implementations I've seen, offering several options for each filter as well as the ability to shoot one scene and have the camera automatically apply every filter. It also has Olympus' highlight/shadow curve button for adjusting curves rather than just shifting the overall exposure; that doubles as a programmable function button.
If you buy the kit with the new power zoom lens, I really suggest to spring for the optional Auto Open Lens Cap. While it's annoying that it costs extra, it's a lot more convenient than easily-lost lens caps.

In addition to stuff I've already mentioned, the E-M10 has a lot of useful features, including time lapse and auto HDR, along with Olympus' nice set of in-camera effects. Like most low-end time-lapse implementations it's limited to 99 shots and 3 frames/1 EV for bracketing, though if you use the auto HDR it can combine up to 7 frames/2EV or 5 frames/3EV. There's a new high-speed mode for the viewfinder that drops the resolution in exchange for a faster refresh rate as well. It seems to automatically down-res during continuous-shooting if turned on, which is disorienting at first but nice to have.
The Wi-Fi implementation is quite well-done, though not without its problems. Instead of near-field communication (NFC), the app scans a barcode that appears on the camera and automatically configures the connection; basically, it saves you from having to enter a passcode on setup. The drawback is that this method requires that you manually switch Wi-Fi connections in the phone's settings each time you want to connect. On the other hand, iOS devices don't support NFC anyway, so only Android folks lose some convenience.
Olympus offers one of the better apps, on both Android and iOS (sorry Windows Phoners). It supplies full live-view remote control -- including zoom if you have the power zoom lens -- for all the settings on the mode dial; the ability to browse and download images from the camera; image editing; and geotagging. As far I could tell, however, you can't change the metering setting remotely. PSA: On Android I did run into a conflict with LastPass (here's the fix) and some phone-based annoyances (I'm not sure if it's HTC Sense or Android) related to connecting to a Wi-Fi access point that doesn't have Internet access -- like a camera. But it still works.
For a complete accounting of its features and operation, download the E-M10's manual.
Conclusion
(A note on the rating: The image quality and performance subratings fall squarely between 7 and 8, so I calculated the overall rating as if those subratings were 7.5 each.)
Unless you need the weather sealing, extra-power image stabilization, or the microphone input of the E-M5, the E-M10 is probably a better deal; it's cheaper, delivers better performance and comparable photo and video quality, and has a broader feature set which includes a built-in flash, 1080/30p video, better LCD and built-in Wi-Fi. If Olympus drops the E-M5's price again -- which it probably will when it finally decides to kill that model -- it would end up a great deal at, say, $499 for a kit if it ever drops that much.
The E-M10 also makes a nice alternative to a dSLR if you want something significantly more compact. It just can't match a camera like the less-expensive Nikon D3300 for low-light photo quality -- the D3300's larger sensor really does confer an advantage there -- or for continuous-shooting performance. On the other hand, it does have a broader feature set than most entry-level dSLRs and for people upgrading from a point-and-shoot the electronic viewfinder and fast shooting with the back display will probably feel more natural.
