Can You Trust Autofocus with Your Digital Camera? by Darwin Wiggett
I was testing the sharpness of a couple of Canon lenses the other day when I discovered something that blew me away.
I got much sharper photos by manually focusing my lenses than if I used autofocus!
Right away I thought something must be wrong - the camera must be at fault (maybe that rear focus problem that has haunted some Canon cameras) or maybe the lens was faulty or something like that.
How could manual focus give me significantly sharper results than autofocus?
Well after testing all my lenses on two camera bodies (a Canon 1ds Mark II and a Canon 1ds Mark III) and then testing my girlfriend's Nikon D200 with several of her lenses, the conclusion remained the same . . .
