Verdict

The Olympus OM-D E-M5 Mark III is a compact Micro Four Thirds mirrorless camera featuring a 20.4MP Live MOS sensor and a TruePic VIII processor, capable of capturing Cinema 4K video at 24p and 30 fps bursts with its electronic shutter. Its standout characteristics include a class-leading 5-axis in-body image stabilization (up to 6.5 stops with compatible lenses), a weather-sealed IPX1-rated body that is dust, splash, and freeze-proof, and a 121-point all cross-type phase-detection autofocus system. Main pros are its lightweight, highly portable design, effective stabilization for handheld shooting, and versatile features like Live Composite and 50MP Tripod High-Res Shot. Cons include a shorter battery life (rated at 310 shots), a primarily polycarbonate (plastic) exterior compared to its predecessor's metal build, and the use of an older Micro-USB port instead of USB-C.
