RE: Digicam vs. Scanner resolutions

["gary" <gsellani@xxxxxxxxxxxxx>]

While the lens+film can exceed 100 lpmm, rarely is the image that well
focused. Here is my favorite page on this subject:

For really sharp focus, you need a magnifier. The 6x of the DW4 on the F3 is
great for such work.

However, if you are in a hurry, their ain't nothing like a Canon EOS USM
doing the focusing.

A digital camera doesn't have the mirror shake problems, which is one thing
in it's favor. Further, you just have the CCD resolution to consider, while
the 35mm film plus scanner has to contend with the grain of the film and the
resolution of the scanner.
