I have a Canoscan 9000F MKII. It’s convenient, flexible, and does a nice job on scanning prints, but for high quality scans of negatives and slides it’s nowhere near the actual resolution of the dedicated film scanners. Yes, it can produce big files, but those big files don’t have a lot of detail. Something like a Plustek or a Pacific will pull easily double the actual resolution of our a negative. It will take a lot more time, too but if you want to scan negatives to get files that can hold their own against modern digital cameras, a Primefilm can do that, and the 9000F cannot.
