Railfan Technology > Kodak Projector LensDate: 06/08/21 20:37 Kodak Projector Lens Author: KM-ML4000 I am looking for lens recommendations for my Kodak Ektagraphic III AMT Carousel projector. I am looking for a non zoom lens suitable for home projection on a 70"x70" screen. There are so many different lenses, I haven't a clue what to buy.

The closer the projector is, the shorter the focal length has to be to get the same image size. Here are two resources. The first is a pdf chart from Kodak. The second is an online lens calculator.

It’s been out of production for years but you can find one with an EBay search. Perfect for home use and very sharp!
