[Frameworks] wide angle projector lens?

[Scott Dorsey]

I think Buhl made a half-inch lens for the B&H projectors.  It was ungodly
slow and had awful edge-to-edge sharpness but it sort of worked.

I may have one around somewhere, I will have to look.

Bell and Howell made a 5/8" lens for in-flight movie systems on airplanes.
It also had sharpness issues and a lot of barrel distortion.

You could try asking Neil at Cardinal Sound and Motion Picture in Maryland
about renting super wide lenses.  301-621-2500.  I know that they have at
least some B&H 5/8" lenses in their rental stock.  I worry, though, that you
are going to wind up spending an awful lot of money for very poor image
quality.

You might be better off with a couple of large front-surface mirrors and a
1" lens.
