For me, selecting AF points takes too much time. I simply centre on the subject (running diagonally towards me) lock the focus with my thumb on a focus lock button, re-frame and fire. The whole operation takes less than 1 second. In that time, he has travelled about 6 feet. In the event, I would most likely have him framed big in the finder, so would not need to recompose. The central AF sensor would be covering him as the subject, in which case I would not necessarily lock focus. Does this make sense? Cotty ____________________________________ Oh, swipe me!
