I tried to do a test 1meter distance, tripod. And I used a sort of "scale".I took a few test shots with my RF 70-200 just now, all of them hand held, at close distances at 200mm. From what I can see, the focus isn’t all that consistent. Some where in perfect focus, others where slightly out of focus. I can’t rule out user error, but it seems that focus can be a bit hit and miss at close focus distance, and 200mm.
I haven’t had enough experience with the lens to tell if this will be an issue for me, or not.
Edit: I did a better test, sitting down supporting my hands. At 200mm and 0,7 meters, I get sharper focus when using MF and focus peaking. When using AF in the same scenario, it does seem to front focus a few mm. The sharpness difference though, isn't that significant. I am not sure I would ever notice it if I didn't look for it. The "out of focus" shot still shows much finer detail than I am able to see when using my own eyes, going as close as I can. I doubt that this will be a real world issue to me.
I am really really enthusiastic with the Canon r , my RF 35 and the RF 24-70mm are superb.
But to be honest, there rest some doubts about the RF 70-200mm lens and I will be sure if this huge amount of money will be worth it, or better to send the lens back...
