Q: Do I need an anamorphic lens with a 16:9 aspect ratio Lunette Series screen?

No, an anamorphic lens is not required for a 16:9 aspect ratio screen. You would only need an anamorphic lens to “stretch” your 2.35:1 image onto a 2.35:1 aspect ratio screen when using a 16:9 projector to eliminate the top and bottom black bars.
