The point is that rolling shutter happens with mechanical shutters, that's actually where the term comes from.
That's correct, indeed it does, but do you see sports photographers having rolling shutter issues with the mechanical shutter? I don't. So, if we have an electronic shutter that's as fast as a mechanical shutter, which has been the industry standard for decades, and is proved to be competent...problem solved, no?
I'll take the high ISO performance and extra dynamic range any day over dropping to APS-C performance level. We "all" go full-frame for a reason, right?
I'll also take the ability to shoot in a audio recording environment without disturbing anyone, the smaller delay when pressing the shutter button, the extra framerate for burst shooting, etc
Others will take the ability to shoot wildlife without disturbing their subjects, for instance, not to mention pre-burst shooting.
the R6-III seems to me to be a dud when compared with what Sony & Nikon are delivery at the same price point or level of camera.
So, what are Sony and Nikon delivering at the same price point, that Canon will not, if the R6 III comes out according to these rumors? I see an a7 IV and a Z6 III. One has a higher resolution sensor, but shoots at 6fps mechanical and 10fps electronic, with considerable rolling shutter, and the other one features a
half-stacked CMOS sensor. Sounds to me like this R6 III would be packing the most advanced sensor and autofocus technologies, among those three cameras.
