[pure-silver] Re: Enlarger lenses

Nikon made a nice length enlarging lens that I have used for 35mm film - 63mm. f2.8 I believe. 

A little longer than 50mm, but not so long as 75-80mm.
Thanks Clifford. Well, you confirmed my suspicion that modern lenses are still subject to the same sort of manufacturing variations that have always plagued the ilk. The Comparon was Schneider's economy lens, not to be confused with the Componon. I have an Enlarging Rokkor, its an excellent lens, I think a Heliar type similar to the Kodak Enlarging Ektar. I am a but surprized by the performance of the Biotar since fast lenses tend to be more critical of distance than slower ones. The same for wide angle lenses. One problem with WA enlarging lenses is light fall off. I have a 135mm Componon I use for 4x5 and have to burn corners. If I could I would use the next longer lens for each size, i.e., 75mm for 35mm negatives, 105mm for Rollei negs, and 205mm for 4x5. That takes a long projection throw.
