My 35L is front focusing when I used the focus point all the way on the right of my 5DII. is that the 35L's issue or my body? It hunts when I use that focusing point and takes forever to lock on sometimes. When it does lock on, it'll front focus. The middle focusing point is spot on though.
I use the 35mm f/1.4L for belly dance club work on the 7D, and sometimes on the 1D Mark III. This is generally low-light photography. I work in M mode, and use selective AF, programming the focus point with the multi-controller to place a focus square directly over the belly dancer in the frame. I do this dynamically, in realtime, during a show.
I've never had any of the problems you are describing. I can use any focus point on either camera, and get a fast, accurate result. Both the multi-point diamond on the 7D, and the ellipsoid on the 1D Mark III work well.
Now, each of these camera system is using less of the lens than the case for your 5D Mark II ... as the 7D has a 1.6X FoVCF, and the 1D Mark III has 1.3X FoVCF. Now, this got me to thinking. Could it be you have some vignetting going on for the right-most focus point? Could a bit less light at the edge maybe tripping up the AF sensors on the 5D?
Hope you can resolve this ...
