Welcome to my darkroom. All I have here are some notes I gathered off the net that I do not want to loose. I have not validated any of it so take it with a big grain of salt.

I have always used a 50 mm lens on all my 35 mm enlargers. I have a 75 mm lens that came with my Omega B22 that I have never used. I read the following somewhere and have yet to confirm any of it.
