I have a Stewart Vertical Masking Electromask Classic(StudioTek 130 G3) that is a 125" 2.35 screen that drops masking on each side automatically for 16.9 movies at 100".
I also have 2.40 programmed so when the aspect ratio changes I just hit the Position button on the remote and select one of the three.
The projector sends a command to the screen to drop the masking when I select 16.9 and then raises it automatically when I select 2.35 or 2.40.
The pj has the ability to memorize 5 aspect ratios.
The picture quality is totally awesome and with the auto zooming lens feature there is IMHO absolutely no need for an anamorphic lens.
I do not hesitate in recommending this setup as to me it is well worth the money spent.
