As before, it's mostly about speed. The sensor, TruePic VIII processor and 121-point autofocusing system contribute to some extremely fast shooting. You can fire away at up to 18 frames per second with continuous autofocusing and autoexposure, or 60FPS with focus and exposure locked. There's also a 120FPS electronic viewfinder, and a Pro Capture mode that eliminates delay by buffering photos the moment you half-press the shutter button. Not that Olympus isn't concerned about quality: on top of a higher dynamic range and lower noise at high ISO levels, you can shoot stills in an effective 50-megapixel mode and record 4K video in the wider-aspect Digital Cinema Standard (4,096 x 2,160). You're paying a premium, but you should be getting a lot.
