The Olympus OM-D E-M1 Mark III arrives as a scaled-down E-M1X: a 20.4-megapixel Live MOS sensor, the TruePic IX processor and a sealed magnesium-alloy body that weighs 580 grams with battery and card. Its five-axis stabilization reaches 7.5 stops when synced with stabilized Zuiko lenses, and 7.0 stops with any Micro Four Thirds lens. The package keeps the compact size of the series and adds the multi-selector lever and joystick inherited from the larger model.
Autofocus uses 121 points combining phase and contrast detection, all cross-type, with face and eye detection that works better than in the previous generation. Bursts reach 18 fps with AF and AE active, and 60 fps with the silent shutter and focus locked. The 50-megapixel handheld High Res mode stacks several frames without a tripod, and Live ND simulates neutral density filters up to five stops with no accessory. The electronic viewfinder offers 2,360,000 dots and the 3.0-inch screen is vari-angle and touch-sensitive.
Video records 4K at 30p, Cinema 4K at 24p and Full HD up to 120p, with microphone and headphone inputs. This is a camera for reportage, nature, travel and hybrid photo-video work, with dual SD slots, a BLH-1 battery rated for 420 shots and sealing down to -10 °C. Against current bodies it loses out on viewfinder resolution and 10-bit video, but it remains a light and tough tool. It belongs to the OM System catalogue, the brand that continues the OM-D line.
