COOLSCAN IV ED (LS-40 ED)
Film • 35 mm film: Positive and negative film, both color and mono-
chrome, 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 op-
tional 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).
