Hello, I got an enlarger as a gift but it came with an 80mm lens. I use a Seagull camera that has a fixed 75mm lens. How does that affect the final print? Also, what lens do I need to enlarge 6X9 negatives? By the way, that enlarger is a Japanese Luminar but I never heard about that brand and I can't seem to find 35mm, 6X4.5 or 6X6 neagative carrier. Does anyone have any information about this brand? Thanks!
