The Olympus OM-D E-M1 Mark III is a new 20.4MP Micro Four Thirds camera with an impressive image stabilization system that compensates up to 7.5 shutter speed stops when paired with a compatible stabilized lens. There are many professional photographic features such as 50MP handheld High Res shot and Live ND. The improved autofocus works for video as well. The camera records only H.264 8-bit 4:2:0 video internally up at to DCI 4K 24fps.

Along with Panasonic, Olympus has been a proud propagator of the Micro Four Thirds system for years. Panasonic, who lately invested a lot into their full-frame L-mount LUMIX ecosystem, has been known for a more video-centric approach to their cameras. Olympus, on the other hand, mostly offered better features for photographers. With the recent announcement of the new Olympus camera from their OM-D line, it seems to continue this trend, although there are some minor improvements in the video capabilities as well.
