Again, this is my experience. Out of a 100 shot burst, I can post 40-50 that were tack sharp as they should be, the problem is that the remaining 50 are not focused. This is with AF priority set, not balanced or release. This is not a shutter speed or technique issue. The Tony Northup review in regard to the AF is my experience as well. As much as I want this camera to work, I can't have a latest tech release Sony body not getting AF correct at 60x/sec on a basic subject moving towards the shooting position with good light and the AF sensor saying it has lock on the subjects eyes the entire time, every frame.
All I'm asking is are others seeing this or are they such huge Sony fan boys, they just can't get past that part. Do they even own the camera and good GM glass or are they just here to argue and defend Sony. As much as I have invested in and love Sony, I'm gonna point out when there are issues. Every camera has a few but Sony built its reputation of AF accuracy and speed. Unless I have a lemon unit (not ruling that out but seriously doubt), this body sadly is not for me for what I shoot. There were even a few shots that were soft of the subject just sitting at 15 yards still not moving. Again the AF point was locked on the eyes of the dog. Somethings not right with the system or my camera, not sure.
I am not surprised at all. The A7iii, A7iv, A7IV / V all cannot achieve high hit rate for subjects close to the camera, moving towards or away from the camera.
Note that birds are not the hardest subject for the autofocus system. A subject stumbling towards the camera, using a f/1.4 lens is a far harder subject because the lens has to move the AF elements a massive amount at close distances.
Since the A7VI does 60 AF/AE calculations per second, this also means the camera is focusing where the subject was 1/60s ago. If the subject has moved out of the plane of focus then you are out of luck.
There is be some amount of movement prediction if you are using tracking, but if you think about it, this only works if the subject is moving with uniform velocity (like a bird)
