Hi George!
Are you shooting 2" in front of the glass or the fish? The autofocus on my
G3 was driving me nuts until a more experienced person suggested putting the
camera right up on the glass to "fool" the autofocus into focusing on the
killie.
The manual over ride on that camera is a bad joke. (What's that phrase about
a fool and his money?) I do like the G3 except for the difficulty focusing
on killies and other fishes. (Wanna see my collection of tail shots?)
All the best,
Scott
Remember on most cameras there is the macro mode which allows you to get
pretty close in most cases. With the Canon powershot G3 shooting 2" away is
no problem.
