are also other good 4000 dpi scanners).  If you calculate the 
equivilant pixel count when you scan a 6x9cm piece of film with a 
4000 dpi scanner, you end up with about the equivilant of a 96 
megapixel sensor (I'm sure someone will get the correct number on 
this.)  Neverthess, it's an impressive number.  I've seen the color 
out of the 11mp Leaf, but they don't seem to show the b&w.  The color 
is excellent, but the b&w may have some issues.  Get a dealer to let 
you scan one of your b&w negs, and you can compare for yourself.
