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