Digital BW, The Print

Clayton's 8/1 post below gives us a some idea of what we can expect 
if we use one of Canon's best lenses with Canon's newly released 
successor to the 10D, which they've called the "20D". It's being 
reviewed now on

and on

<http://www.luminous-landscape.com/reviews/cameras/20d-part1.shtml>

and I think I'm getting excited.
