Depends on what you are going to use it for. If all you are doing is scanning prints it will do an excellent job. I have never tested it with film since it is limited to 4x5 and really is a step under the 'consumer class' photo scanners, all of which have a minimum of a bed that will handle 8x10 film.
If you intend to scan film for prints larger than 8x10 this probably isn't the right scanner. Dedicated film scanners do better for 35mm and MF and while I have no first hand experience, the design tells me it isn't goingto perform up to the standard of the 4990/V700/V750/i800/i900.
