That VERY much depends on the film being scanned, what camera/lense and
development were used.  I find a VERY large difference in quality of 4000spi
scans vs 2700spi scans.  I find the 2700 scans are not very sharp, and don't
have near the detail the 4000spi scans do...and then 5080 is even far better
than 4000.  It also depends on what scanners you are talking about.

How very true!
