Re: Sorry to ask again but...
A few years ago, I did a series of scanned self portraits (my face, not the, er, other end!). The depth of field with my Microtek Scanmaker 4 was considerable. Also, I know 3 or 4 photographers in this area (Atlanta) who are scanning compositions of flowers, and getting stunning results with various scanners. I think many scanners do typically have good depth of field.
