Originally posted by stevebrot My advice is to compare against magnified live view (no focus peaking) as well.
As Steve has said, that's the best way to judge MF focusing, although I tend to leave focus peaking on.
BTW, one observation:
While the split-image KatzEye does help me get sharp MF, using live view with focus peaking seems to be slightly more precise. That is, with live view I can hit exact focus quite readily, while with the KatzEye I can sometimes be very very slightly too close or very very slightly too far -- however, my eyes (now older than dirt) may be a factor in getting exact focus with a split-image finder.
[Another way to say this is that both tools seem to be very high in accuracy, but that the live view with focus peaking seems to have higher precision than the split-image screen.]
I ~LOVE~ nailing the focus with my MF lenses !!!
