I used to think my Epson V700 did a very nice job of scanning my 6 x 4.5 negatives. But I got rid of it and got a great deal on a Nikon Super Coolscan LS-8000 ED and I have to say, after re-scanning some of the negatives I did with the Epson, the Nikon makes the Epson's look like crap. I know, I know, flatbed scanners are not reputed to be as good as dedicated scanners, but I didn't expect the order of magnitude leap in performance that I got with the Coolscan. The negatives with the Nikon at 2000 ppi look better than the ones with the Epson at 4000 ppi. Not to mention that the Nikon has Grain Management software that the Epson did not. I have heard of flatness problems with the non-glass holders, however I did not see a problem with my eyes and at 100% scans, I do not see any difference I would not attribute to the natural falloff associated at the corners with any lens, even my CZ's. Makes me wonder why I wasted so much time with the Epson!
