The answer, in actual fact, is that Nikon can beat Sony at their own game, with the 46MP full frame sensor in the D850 proof of the pudding. It does better 4K video quality than the A7R III at a higher megapixel count and edges it for stills quality too. Now let’s hear about some of the science behind it.
Note: My camera is running firmware version 0.2! If the performance changes when updated, I will re-do the test
Does the Panasonic GH5S finally achieve full-frame like performance at ISO 12,800 against the best of the competition?
Here I put the little nocturnal fox in the ring with the Sony A7R III, A7S II, Nikon D850 and the plain old ‘non-video-orientated’ GH5.
