So i purchased a 70-200 II for my d800 a few weeks ago. It appears that in some situations,the lens back focuses tremendously. The weird thing is it's not all the time. Sometimes it focuses dead on, but in the situations that is does back focus, it back focuses every time. I've attached some 100% captures showing the focus points and you can see the problem. It most definitely seems to only be in the longer focal lengths. Should i just return to B&H and exchange for another copy? i still have a few more days to RMA it. I also don't find the autofocus to be all that much quicker to attain (wrong or not) than the 70-300 4.5-5.6. Granted I know these pictures aren't great. They were shot at 2.8 rather than stopping down some, but still focus shouldn't be off that much. I have several more shots of this goose and they shouldn't all be this bad.
Misfocus at 190-200mm
Much Much better focus at 70mm
