[1] Released on February 28, 2020, it replaced the Olympus OM-D E-M1 Mark II.

The E-M1 Mark III follows the E-M1 Mark II in embracing artificial intelligence-based features such as a deep learning autofocus system and multi-shot image processing to simulate neutral-density filters and a hi-res mode that allows the 20-megapixel camera to produce 50-megapixel images while handheld and 80-megapixel images while being on tripod.

[citation needed] The benefit of hi-res mode is bigger resolution, low noise and an increase of dynamic range.

[6] The camera took criticism for including the same 20-megapixel sensor, electronic viewfinder, and screen, as its predecessor, the Mark II.

The same sensor is also present in the enthusiast-level Olympus OM-D E-M5 Mark III which was released just months earlier.
