Originally posted by Marc Sabatella I'm also going to guess that the MF was easier on the MX than on the K10D. And I'll also suggest the possibility that the pixel-peeping possibilities digital have caused us to become *far* more sensitive to slight focus issues, motion blur, and so forth than we were when for the most part we were judging our results based on 4x6 prints.
This is probably right -
but with the smaller than full-frame sensors and shorter focal length lenses - the depth of field is greater for any equivalent angle -
most pre-focussing is done mostly with depth of field making up for lack of precise focus -
and with most true action shots focus is never precise - since the subject is moving and even with the fastest AF in the world we are still talking about 0.3 secs -
which at 60mph (cars) is a movement of 26+ feet! -
so pre-focus and anticipation
is required -
hence experience > fast reaction + faster AF??
