I would love to take you up on this.. Not to actually prove you right or wrong but to see if my scans come anywhere close to yours. I have a v600 for MF, and I made a rig to scan with my em5ii. The em5ii wins in details (high res mode), but maybe there is something up with my v600. I use vuescan and ensure it adjusts focus every time. I have used different holders and ANR glass.Hi
again I will offer to anyone who wants to compare their camera rig with my Epson flatbed scanner. I'll post them a negative 120 roll or 4x5 sheet if they promise to post it back even if they're too slack to get around to (or embarrased to get around to) publishing the photo results.
I will also say I can "scan" a roll of 120 in about 2-3 mins with my em5ii, it takes a lot longer on my Epson v600.
