image 1 1/2 times. The Anamorphot was
flipped 180 degrees and mounted on
the 16mm projector, resulting in a 1.85:1
projected image. The Moeller Anamorphot
may be exactly what you're looking for, and
although they're no longer made, they are
reportedly available on the used market.

"Although I've heard this many
times, it seems misleading to me, because
the angle of view is not the same in both

still camera, you must use a 16mm lens on

same angle of view as a 35mm lens on a
35mm still camera. Continuing, the 'normal'
