Hi all, After much consternation and dabbling in all kinds of digital solutions, I've finally settled on a Nikon D810 as my main camera, in part due to its resolution to double as a copier for my negatives. Right now, I just have 35mm but am thinking of moving up to 120-- probably 6x7 or 6x9-- as I really want archival black and white. Will be using 55/3.5 Micro lens with extension tube as needed. Not having started to copy yet, may I please ask, what is your experience with copying 35mm negs compared to 6x7/6x9 negs with a circa-2017 high-res camera like a D810? At what size print enlargement did you say, whoa, major difference!? Even though I'm sure there will be a lot more information on the monitor when comparing 35mm to 120, reality for me is that if i can see no incredible difference in, say, up to 2'x3' prints, I don't know if I'd spring for 120. Your thoughts, thanks!
