Hi! I own a Nikon 8000 for 6x7 color transparency scanning and in general am quite pleased with it. I use the scans to make 20x25in prints on my Epson 10000 and get great detail, etc., from the scans. However, let's say 10-20% of the time, my scans are unusable because the film was not flat enough to give good focus. I find the film stretching feature of the MF holder to be very fussy. I have subsequently learned to tell lack of focus by doing several focusings in different parts of the color transparency and comparing the focus numbers. The glass-covered rotating holder has been recommended to me and I am seeking further comment. I suspect that the focusing problem would be solved by the holder, but am concerned whether the extra two sheets of glass will degrade the scan in any way or create newton rings or other artifacts. And whether I can expect the glass carrier to last for a long time given reasonable care. Does anyone in this group have experience with the glass-covered holder? Also I can't really tell what the "rotating" feature is all about and why I should buy this one (as recommended to me) rather than the less expensive regular glass-covered holder (or if I should consider either of them).
