Beware with AFD that screwdriver focus isn't as accurate consistently as AFS unless you focus away and then reaquire focus. If you focus on the subject and then refocus without defocussing with AFD I find it can miss focus

I notice this especially with my 105 f2DC, I find it immensely frustrating with its focus misses - shooting in artificial light, incremental focus, less than sellar consistency in focus (but when it's right, wow,I just find it tough to be consistent with it)
