I used focal pro and tried 8 times using a gazillion shots and it always said -11 was the correct adjustment. I picked up a spider lenscal target and -11 was off quite a bit. -4 seems just perfect. I have since used focal again and it still says -11. anyways , see if you can tell which pic is from which camera before looking on flickr.
I think you need to AFMA Focal Pro.

Seriously though... you should call Focal and see what they say. That is a lot of time you wasted.
