I just bought a speed graphic but I don't have a lens and I probably won't for some time until the meager camear budget recovers. I do have a Fujinon 75mm and some other 135mm enlarging lenses. I'm not sure, but I think they should work, but there is probably some way in which they are suboptimal. Is there anything different about enlarger lenses that makes them worse for using on cameras? If so what is it?
