I have been using a Fujinon-EP 80 lens for printing 35mm and 120 and have now noticed quite a bit for fungus on one of the inner elements. I also have a Fujinon-EP 135 that i use for 4x5 and was wondering if i can use the 135 for all formats until i purchase another 80 lens? Will i experience any issues using the 135 on 35mm or 120? I also have 2 El-Nikkor's 50 f4 and 2.8, Could i use thoses for 120 negatives? Thanks!
