I dunno - sports in particular are easy to predict, as Ron's already 
outlined. Canon's USM focusing is very fast anyway.

Oh the *only* way to play. The best way to get compliments on your 
photography is to never, ever show anything that's not up to your ideal

High enough for me - my standard setting is (iirc) 1760x1360 JPEG, 
resulting in a ~900k file. This prints nicely to A4 without any 
noticeable artefacts (Epson Stylus Photo 950... yum). There's also a 
neat Photoshop filter that fractally upscales images without 
pixellation - I've had *really* big prints done from this (and smaller) 
resolution originals[1] and they've been fine.

digicam got dropped on the floor (ouch), so had to rely on PhotoCD from 
my bro-in-law's film camera. Nowhere I went to seems to do the old 
Kodak PhotoCD - they all push their own crappy consumer quality - and I 
ended up with about 800x600 at a *really* dodgy quality. Photoshop++
