I looked it up here and got an even greater depth of 30 cm. http://www.dofmaster.com/dofjs.html I was wondering why none of the brilliant minds here had challenged Brian's figure of 22cm. Such a large number seems so luxurious to me - I'm usually working with a couple of millimeters at close distances. :-( :-D So have we decided that shooting candles (rather than by candlelight) ain't the way to get the best out of an M8 yet? I'd really like to see some up close focus test shots. It's so boring doing this with film. Regards, Rick.
