My limited experience with the 135 f2 and and lesslimited experience with the85 f1.2 on FF suggests that, overall, I like working with the 135 f2 more for reasons previously stated. The 85, optically, is fantastic, but it's a tank, the autofocus is slow, and I'm not a big fan of the electronic manual focus. I'm stepping out on a limb, though, because I'm assuming that the 135 f2 can autofocus correctly when calibrated. Both copies I've had so far have had backfocus issues with both of my bodies, so I'm going to send the last copy in for a factory visit with my 5D so they can do it right. I've been willing to work around the backfocus for a few days to play with it, and love what it does otherwise, but....


can somebody reassure me that the 135 f2 can in fact autofocus correctly, and that what I'm experiencing is most likely a calibration issue? I'd sure feel a lot better []
