I've got a Canon G3, myself. The G-series has a macro mode that gets
down to 2 in, plus a manual focussing mode. An f2.0 lens makes it a
little faster than most of the competition. Has an external flash shoe
and you can get accessory bayonet snoots for using regular screw-in
filters and close-up lenses.

Sure would be nice to adapt a bayonet lense mount to a moderately-priced
digital. I'd love to use my old Pentax-mount SLR lenses on a digital
body. Anybody here tried that?
