You are correct, Conrad. I print full frame. I was not aware that there is a Nikkor EL 63mm enlarging lens. I'll look into that, also. It is an unusual size for an enlarging lens. Do you happen to know Nikon's reason for this? I also apologize for posting this on the "film" section. I meant to have this in the "printing" board, but forgot where I was after surfing and reading for two hours.(posted 8906 days ago)
