What is peculiar about enlarging, copying, or photo copy lenses that might make them unusable for camera use? I use focal plane Graflex cameras and I have seen lots of these lenses at shows for good prices. I bought a 111mm Kodak tele FluoroEktar f1.5 for $12. Even if it is unusable it is gorgeous. The glass must be 3" across. It will cover a 2 X 3 with a little space to spare. I also have a Kodak 21.25" f11 Ektanon. It is beautiful too and was only $20. Again, I bought them because I couldn't help myself, and because they were so beautiful. So anyway, can I use them for shooting photos? Also does anyone know what it is that makes a FluoroEktar different from an Ektar, and what does it mean when they add "anon" to the end of Ektar etc.
