Lynn, we're talking about optical zoom, 
within the scanner's optical system.  
Nothing to do with the "zoom" you do in 
the preview window of the scanner's driver.

It does appear, as Art pointed out, that 
most scanners don't have an optical zoom, 
but that possibly the Minolta film scanners 
do.  (The "evidence" being different 
resolutions for different film sizes.)

The Agfa 2500, AFAIK, is a scanner with 
two optical paths.. yet another hybrid.
