Dear All,
I hope everyone is keeping well?
I am wondering if someone can solve this frustrating issue for me...?
I have a Canon 5D mrk iv with these 3 lenses :-
ef 24-105mm f/4l is ii usm
ef 16-35mm f/2.8l is iii usm
ef 70-200mm f/2.8 is iii usm
My issue is, when I attach and start using the 200mm, even with auto focus and image stabilization on, the focal point of the image isn't perfectly clear once I put on my laptop, even at 70mm range. I previously used this lens with my Canon 5D mrk iii, and have no issue with the focusing.
Strange thing is, both the other 2 lenses with the mrk iv, there is no issue, the images are very sharp on the big screen. Its just the mrk iv & 70-200mm combination I am having trouble with.
Can someone please help??
Many thanks in advance.

I had a chance to go out and shoot today with the adjusted lens callobration. Unfortunately its still terribly out of focus, i am a track and field photographer so i photograph fast moving objects, I had the shutterspeed at 800 but still blurry. I attached onto my 5D mrkiii and was perfectly sharp!
I am really lost with this, all my other lenses i tried with both cameras are fine, and the 200mm on the mrkiii is fine, its just the mrkiv with the 200mm is the issue...

First and foremost, I would reset and clear out the focus adjustments. I think entering AFMA settings should be a last resort, not a first option. Besides, it is all too easy to enter a bad set of adjustments. It takes a little practice to get it right.
Can you post a sample image that demonstrates the issue? It would be helpful to know the exposure settings, as well as the camera settings like AF mode, drive mode, active AF point(s), as well as the focal length. Basically, the EXIF data.
BTW, I shoot track and field, too. It is a pretty easy sport to shoot.
I had been hoping to see this young lady at the Tokyo Summer Games this year.
