Sony's on a bit of a roll at the moment. It seems like just yesterday it was launching the A7V (it was actually late last year – how time flies), and it’s now followed that up with the sixth generation of A7R. The A7R has long been the go-to full-frame camera for anyone who prioritizes outright resolution, but by going north of 60 megapixels, recent A7Rs have been compromised in other areas. There's the obvious issue of huge image and video file sizes, but the drawbacks of such a high resolution come in other, more subtle forms.
