Originally posted by pawel.z raphtze, you can also use LiveView. It should be better than manual.
fortunately, liveview works well and achieves good focus. however, it's cumbersome for me to use--i'm coming over from film SLR and i just like using the viewfinder better. i used to shoot weddings with my film SLRs....and i cannot imagine using LV for shooting tons of frames. well, it's ok.....to be honest, i'm just a casual snapshooter these days
so liveview and/or manual focus, i can live with. i also used to shoot CART open wheel racers--and my tactic to achieve a sharp picture would be to pre-focus manually and pan--no need for AF
my main film SLR was the PZ-1p, with SAFOX II....while it was slow, it was quite accurate no matter what AF lens i slapped on. for the life of me, i'm not sure how AF could 'regress' in these DSLR's (i'm getting a crash course learning about all the subtle nuances of DSLR photography)--of course, i'm no engineer either, so i don't know what the challenges are between film and digital cameras. if i'm repeating some old points, i apologize
