Q: I have a 16:9 (HDTV) home theater projector but I’d like to have a presentation that has a 2.35:1 (Cinemascope) aspect ratio on a 2.35:1 projection screen. Do I need an anamorphic lens for this?

For the best possible results, an anamorphic lens is recommended.  However, it is possible to get a 2.35:1 screen format as long as you can live with the “black bars” created when a mismatched 16:9 native aspect ratio projector is set up to fit a wider projection screen format.  It is simply a matter of personal preference.
