Hence, on that site they would conclude that if you have a fine lens, AF would take away most of its qualities by lousy focusing. I thought of it, and it seems total BS (BackSpace <g>) to me.
REPLY: How many l/mm can your eyes detect through a viewfinder? One thing is test set-ups another is reality. Most subject are three dimensional and minute differences and inaccuracies are covered by DOF both with AF and MF. Detecting more than 50 l/mm for moving subject is impossible for most of us....At least it is for me... The 50 l/mm thinghy, and such tests, becomes totally academic when you shooting a moving animal frame filling at F:4 with a 600mm lens with the associated miniscule DOF. AF will get you the shot.
