Originally posted by c a sugg I have the 4490 and like it, though I do have a couple of issues:
Especially with mounted slides, the driver arbitrarily crops in -- quite a lot. The work around, as stated above (in regards to 120 film) is to toggle off thumbnail and manually crop in to the full frame.
The other drawback is how seemingly fragile the carriers are. Though mine are holding, sooner or later, I'm fairly sure they will give out in some fashion. As far as I can tell, there are no replacements available
Considering your comment about the fragile carriers, I thought, "What if my carriers were broken beyond repair, and I could not find replacements, would I still be able to use the V500?" So, without using the carriers, I started placing 35mm negatives in the center of the glass in two rows. I noticed that the glass window in the top is full length, so I found I could easily fit 12 35mm negatives in the scanned area. I tried a scan, and it did not automatically find the frames in "Thumbnail" mode. However, by turning off thumbnail mode and manually selecting the frames with the marquee tool in the preview window, it had no problem scanning all the negatives. They came out fine, but the film did not have very much curl so laid fairly flat. Ideally, I think I would make a holder using some poster board and maybe a transparency film to hold the negatives flat if they are badly curled. Or better yet, just carefully cut out frames from the cardboard which will mimic the stock film holder, but allow for 12 negatives rather than 8.
This scanner may be more versatile than I thought - 12 35mm negatives at a shot is pretty good for volume processing!
