Hi there, I'm pretty new to printing (haven't done it sine a class I took a few years ago) and I am building my own dark room. I've got everything in order, just need an enlarger lens that works. I read on a forum that the Nikkor 50mm f2.8-f16 enlarger lens works fine for 35mm film. I just got one in the mail and it only focuses the image if my enlarger head is about 2 inches away from the board. Any idea whats up? And any suggestions of what lens I should get? Cause i've tried everything to get this lens to focus while making a decent sized print and it doesn't seem to be happening. If it makes any difference, I'm using and LPL saunders 670 vce. Any help or tips would be greatly appreciated!
