Summary: Like other interchangeable-lens cameras, the Olympus can shoot both JPEG and RAW files, for maximum editing flexibility. It likewise sports plenty of special effects (you can make your photo look like Pop Art, Grainy Film, etc.) along with 3D shooting, sweep panorama and handheld night modes. There's a built-in microphone, but no microphone jack; you have to buy a $90 adapter to use an external mic.
Pros: Compact and easy to carry, Speedy performance with DSLR-like image quality and controls, Tough magnesium body is dust- and splash-proof, Biggest lens selection in its class
Cons: Continuous autofocus balks at tracking moving subjects, Some find controls small and tedious to set up initially, No ISO 100
Summary: Since its debut last year, the Olympus OM-D E-M5 has won many accolades and numerous awards – and it’s easy to see why: this is a camera with a wealth of features, catering to ambitious photographers who are looking to reduce the size and weight of their gear without sacrificing quality. For the most part, the E-M5 delivers.
Summary: The high-resolution sensor of the E-M5 delivers quality that rivals DSLRs. It shows very low image noise until ISO 1600 and remains usable up to ISO 12800 for mid-size prints and 25600 for small ones. The exposure system is really good and automatic white-balance is great. Color accuracy is not perfect but not entire off either. Although there are some quirks to the E-M5, it is the most advanced mirrorless camera available with only much larger competitors.
Pros: Excellent image quality, Very good metering, Reliable Automatic White-Balance, Superb built-in stabilization, Virtually no shutter-lag, Fast contrast-detect AF, Good shot-to-shot speed, Very responsive, Excellent automatic, Unique, Highly customizable interface, Instant video recording, Excellent build quality
Cons: Poor color accuracy, Low-contrast EVF, Not always, Modal Exposure-Compensation, Some tiny, Uncomfortable eyelets, Poorly placed tripod mount, Low battery life, Rear control-dial uncomfortably high
Excerpt: The camera itself is an unalloyed pleasure to work with. No, it's not perfect, and there are some handling issues, mostly related to the fact that the camera is so small. So small, I don't even use a neck strap. A wrist strap is more appropriate, as even with a largish zoom the camera can be held in one hand all day.
Excerpt: With an honest, throwback design the Olympus OM-D E-M5 ($999, body) builds off of the 40 year-long lineage of OM SLR film cameras. Modernized in Micro Four Thirds format, the 16.1 megapixel shooter comes paired with a built-in electric viewfinder (before you groan, take note of its 1.44 million dot resolution and 120 fps refresh rate), 5-axis Image Stabilization, and the world’s fastest auto-focusing system.
Excerpt: Olympus today announced a new Micro Four Thirds body, the E-M5. It is the first in what Olympus is calling its OM-D line of Micro Four Thirds bodies. A new lineup that is intended to attract a more advanced user group than the existing PEN line. As you can see, it is styled after the classic OM line of film SLR’s.
Conclusion: If you can afford the EM-5 and you’re in the market for a MFT, yes, you should buy it. That might sound a little niche, but MFT cameras are becoming insanely popular and insanely expensive, so there’s real demand for what Olympus is offering here. The OM-D E-M5 is an incredibly capable, fun camera that you won’t easily tire of.
Pros: Great battery life, Superior image quality, even in low light, You can really push ISO without sacrificing resolution, Durability, Very powerful auto-focus and image stabilization technology
Cons: Button design, No pop-up flash – accessory only, There can be some in-camera digging before you get your customized settings up and running
Conclusion: There's quite a lot to like about the OM-D EM-5. If I had to mention something negative, it would be the small buttons although they do allow for a larger screen so it's really more of a positive trade off than a minor gripe. The flash is is a little fiddly too, though as mentioned it can be upgraded to a more powerful sturdier built one for more serious situations.
