I'm sorry, I guess I was not clear in stating that.
I meant before the repair, and AF appears to be slightly better now.
As I was saying about reach being number of pixels on the subject, if I did a sever crop before, you could tell the difference in softness. But now if my technique is good, a severe crop is almost usable without tweaking the sharpening as the bird crop shows. I don't recall being able to go that far prior to the repair.
I just went out today to play with my new Bigma and was rather pleased with the results even with 100% view. I even got some decent BIF's (although I still need a lot of practice with that) that I never could do before the repair(not sure if I just got lucky, or the AF system was functing better).
