monochrome, may be used. Film may be
scanned in strips of up to six frames or
mounted as 35 mm slides using mounts of
from 1.0 to 3.2 mm in thickness and 49.0–
50.8 mm in width.
• APS (IX240) film: APS film cartridges can be scanned with the
optional IA-20 (S) adapter for APS (IX240) film.
• Prepared slides: Prepared slides can be scanned using the op-
tional FH-G1 slide holder for the MA-20 (S).
