I've purchased FoCal to run tests on all of my lenses to see if I could figure out at least a single focusing sensor that I can use safely with this camera. At this point I run through adjustment process for 2 of my lenses - 50 mm and 70-200 @ 70mm for each of three sensors - right, center, left. The results are sort of resemble my own findings - both lenses have left and right sensors very close to each other in terms of performance while center is severely out of alignment (I proved this with test shots for each sensor applying AF Fine Tune):
50mm: Left -1, Center +9, Right -1 70-200 @ 70mm: Left 4, Center 11. Right 5
Pretty much at this point I have to use AF Fine Tune for a specific sensor and always use that sensor. Forget any sort of advanced focusing with this camera.
