Customer Question

Hi, there, I am using Canon 5D mark III and Canon EF 70-200mm F2.8 IS USM. I found there is a AF problem that the focusing point is before the target. I tried to DIY AFMA but it seemed that the +20 still cannot correct it. How should I do?

Hello and Welcome to Just Answer. My name is***** can help you with your request.

In order to give you the best advise with this Camera/Lens problem I need to know a bit more information:

- Does it seem to be affected by the distance of the target? or the aperture setting?
