A lens that produces different magnifications along lines in different directions in the image plane.

anamorphic lens

A movie camera lens that horizontally squeezes a wide screen image into a standard 35mm frame. When projected, an anamorphic lens stretches the 35mm frame horizontally and fills a wide screen. This lens allowed the movie industry to make wide screen films with the same 35mm equipment. A 2:1 anamorphic lens squeezes 100% more into the frame than a normal lens. The term comes from the Greek "anamorphosis," which means to "reshape." See anamorphic DVD.


An Anamorphic Frame
An anamorphic lens squeezes the image horizontally in order to fit it into a smaller frame format.
