Our Verdict
Olympus OM-D E-M1 Mark III
OM SYSTEM OM-1 Mark II
The OM SYSTEM OM-1 Mark II is better overall than the Olympus OM-D E-M1 Mark III. While the Olympus model has slightly better ergonomics, the OM SYSTEM has a higher-resolution EVF and screen, along with a more efficient stacked sensor that allows for quicker electronic burst shooting with less rolling shutter distortion. It also has a more reliable autofocus system and better video features.
