So there you have an example of that lack of sharpness I am facing with the R5

Then here's a photo taken with the R5 with the same exposition, so 1/400 f7.1 with the same EF 100-400 USM II lens.

That same story is what I am getting when photographing birds in flight. I used to get razor sharp images with the 5DSR while I am getting disappointing shots with the R5.

The problem can not be the high pixel count, since the 5DSR is a 50 megapixel dynosaur with a mere 4 fps burst at higuest speed if I recall.

I'll keep investigating and experimenting.

Well, it's clearly motion blur, and as its different between the upper jaw and the lower jaw, plus the hand and plant are not affected (though not quite sharp), it implies that the subject is moving. I've had very sharp results with my 10-400 L mkii (now sold) on the R5, with static and flying birds. Not tried any horses though!

I had not considered the possibility that the question could be a horse related issue :)))

Yes, motion blur is what I first thought, but the thing is that there's nothing in focus there. Not even the parts that are not moving (fingers for instance).

It's horse****!

On a serious note: are both pictures handheld? Could be you were luckier in the first shot.

Even though it does look like a motion blur - shouldn't 1/400 be more than enough to freeze it? OP is not photographing running cheetahs here.
