We purchased a Super Coolscan 5000 ED with SF-210 slide feeders, hoping to scan my parents' thousands of Kodak slides. The Super Coolscan worked flawlessly on single slides, but the SF-210 slide feeder simply could not scan more than 2 slides without jamming.The instruction manual does say that the feeder basically works only with Fuji compatible slide mounts, and warns of problems with Kodak and other mounts - but it's buried in the middle of the manual and you don't find out until you've purchased the producdt. I have been unable to find those restrictions mentioned anywhere inthe literature. At nearly $400 per feeder, I would expect it to work - or at least have the sales literature mention its limitations.I complained to Nikon, but never even received an email response. I will never buy a Nikon product again.
