I got back focus problem on my 60D when mountwith the EF 50mm f/1.4 prime lens on my 60D. It It happens at Autowith auto focus mode, even with a tripod. The focus (I use the center point focus) always fall to the back of the subject. theThe actually subject is always blur.
And 60D doesn't have AF micro adjustment which makemakes me very disappointed to Canadain Canon.
