The Olympus E-M1 III is our favorite Micro Four Thirds cameras for stills shooters, as of publication. It's capable of very good image quality and jam-packed with fun and useful features. It's also no slouch when it comes to 4K video capture and offers some of the best image stabilization around. All this in a supremely well-built, comfortable, customizable and attractive body. That said being said, there are more capable, large sensor cameras available for the money.

Action, wildlife, nature and landscape shooters (with high-res mode). Micro Four Thirds shooters seeking the best image quality. General and travel photographers desiring a small kit.;

Those requiring the best dynamic range and/or resolution. Those needing reliable subject tracking;

A technological powerhouse that thinks differently. Sure, its smaller-scale sensor isn't the best in low-light, but the abundance of shooting modes and technologies on offer here superb - as is the exceptional image stabilisation system. The battle between sensor sizes just got more interesting.

Rapid and robust handling; More shooting modes than you can shake a stick at; Excellent image stabilisation system; Refined autofocus system; Great selection of lenses;

Micro Four Thirds sensor size limited in low-contrast light; Default noise reduction too aggressive; Perceived lack of progress in core features; Better viewfinders elsewhere;

The Olympus OM-D E-M1 Mark III has a smaller sensor than competitors, but makes up for it with strong stabilization, smart built-in features for handheld exposure, and weather protection.

Strong in-body stabilization; Vast Micro Four Thirds lens system; Raw capture at 15fps with mechanical shutter; Electronic shutter at up to 60fps; IP1X weather protection; Swing-out touch LCD; 4K video

Subject tracking autofocus not as effective as competitors; Not the latest and greatest EVF; Menu system could use a refresh

The Olympus OM-D E-M1 Mark III ($1,799.99, body only) looks and feels a lot like 2016's E-M1 Mark II, but offers improvements all around, including an updated image processor that adds some new features, including a handheld mode for high-resolution image capture, first seen in the pricier E-M1X. The E-M1 Mark III is a more sensible camera for photographers invested in the Micro Four Thirds system, though, thanks to a more reasonable asking price and a smaller build.A Tried-and-True Form Olympus didn't make a lot of changes to the E-M1's body this go-round. Its general shape and size are unchanged. It's smaller than most SLRs, but still gives you a big, deep handgrip and balances well with available lenses, even the larger F1.2 primes and telephoto glass that's been added to the system in recent years. It measures 3.6 by 5.3 by 2.7 inches (HWD) and weighs 1.3 pounds without a lens attached. It's sold in a black finish exclusively, with pro-grade magnesium alloy construction and e...

Olympus has put together a package that carriers the Micro Four Thirds sensor so much further than any inveterate spec nerd would expect it to go.

The Olympus OM-D E-M1 Mark III is the most compelling Olympus camera yet for pros and enthusiasts. Offering the power of the E-M1X, with the latest TruePic IX processor and in a more compact body, it's a great all-round camera for photography and increasingly for video.

Great build quality and handling; Excellent image stabilization; Very fast burst shooting; Huge array of shooting modes; Improved AF performance for action

Default JPEG noise reduction is too aggressive; Not the best EVF around; Low light image quality due to small sensor

Olmpus released the third-generation E-M1 with highly similar specifications to its predecessor which makes it seem incremental change and indeed it is. Crucially though, this new revision makes substantial fixes to take the Olympus OM-D E-M1 Mark III to the next level, earning it an Excellent...

Class-leading silent 60 FPS drive; Amazing 18 FPS drive with Continuous AF; Best-in-class 5-axis image-stabilization; Low image-noise up to ISO 3200; Reliable multi-segment metering system; Ultra-fast hybrid AF; Virtually no shutter-lag; Excellent shot-to-shot speed; Very well-utilized dual...

Poor Automatic White-Balance; Below average color accuracy; EVF is not Exposure Priority; Highlights clipped on Preview; Eye-Start Sensor exits Playback; Highly modal interface; Non-linear AEB order; Battery-life is below average; Quite expensive

The Olympus OM-D E-M1 Mark III, offers what some might see as an incremental upgrade to the OM-D E-M1 Mark II , however, the E-M1 II (and Panasonic Lumix G9) are still, to this day, some of the only cameras to offer 60fps continuous shooting at 20mp.

Innovative new features including LiveND; Star focus; Exceptional in-body image stabilisation system; New ISO / Exposure compensation buttons; New power options (can run on USB power); 60fps continuous shooting available; Handheld high-res shooting 50mp; 80mp tripod mode; Improved focus including...
