Yes, the Slide Theater has a lense. A lense is required because the film is not the same size as the CRT raster.

I only saw a Slide Theater in operation once, when we had one in the lab for evaluation. The picture quality was OK (though not as detailed as the slides themselves), but the thing that was most bothersome to me was cropping off the sides of the slides due to the different aspect ratio compared to the TV. I don't recall it having any customer adjustment for overscan. Do I remember correctly?
