I have the Panasonic AE4000 and I have it set up to auto zoom for 2.35 CIH. It works incredibly well with perfect focus, zoom, and vertical position every time. I only had to program the lens memory once, and I have stored positions for 4:3/16:9, Todd AO 2.0, Cinemascope 2.35, Cinemascope 2.55, Technirama 2.65, and Cinerama. All projectors should have this feature. Once you experience it you forget all about anamorphic lenses!
