I got a Kodak Carousel 4600 projector, for free, from my work. It all seems to work well enough. I have read, here, and in other web places, that the stock lens is not that great. Since it would cost quite a few bucks to get a Leica projector with the well reviewed 90mm lens, that's out of the picture. However, I have found there are other lenses I could use. Which ones are good ? It's just for personal veiwing, not for some business slide show.
