If you are projecting only cardboard or plastic mounted slides, I
would recommend a curved field lens. The difference in performance
between Kodak's 100mm (or 102) and 100-150mm (or 102-152) is minimal
- both lenses are decent, but if you care about projected sharpness,
I would look elsewhere for a lens, maybe to Schneider's AV-Pro line
(don't bother with the cheaper line), and others (my Schneider PC
60mm f2.8 is very noticeably sharper than the Kodaks).
Hope This Helps
