I appreciate all the feedback to date. It seems that the SS4000 is the "tried
and true" choice, a scanner with a track record. Roger's point about software
being no substitute for resolution/dpi is well taken. Does the stated
manufacturer's dpi spec. correlate exactly with how many lpi you get in the
final scan? (I noted in a Pop Photo review the IV ED's "optical resolution"
was 53.3 lpi while the nikon 4000 was 60 lpi, so despite having roughly 75%
of the 4000's stated dpi it achieved roughly 90% of its optical resoving
power...hmmmm, is this a meaningful test?) The SS4000, not being a recently
released scanner was unfortunately not included in their testing.
What would really be nice at this point would be a head to head comparison
between the new Canon 4000 and the SS4000...At this point I am leaning toward
the Canon because of its FARE feature. But, it has only been out for a few
months so has had little time to be evaluated by many users.. I'm a little
nervous about being an "early adopter"
