1. An apparatus comprising:
- a lens body configured to fit within a standard digital cinema camera, the lens body comprising;
a dual parallel channel anamorphic horizontal multiple times optical squeezing lens arrangement comprising two optically identical parallel axially aligned arrangements of elements comprising a first plurality of lenses and prisms aligned along a first axis and a second plurality of lenses and prisms aligned along a second axis; and
a sensor; and
off-axis optical components comprising prism components configured to receive two received images separated by an interaxial separation distance, the off-axis components configured to provide the two received images to the first plurality of lenses and prisms and the second plurality of lenses and prisms such that a first received image is provided to the first plurality of lenses and prisms along the first axis and a second received image is provided to the second plurality of lenses and prisms along the second axis, wherein the first axis is separated from the second axis by a separation distance less than the interaxial separation distance;
wherein the prisms of the first plurality of lenses and prisms comprise at least one forward prism away from the sensor and a plurality of rear prisms proximate the sensor, the prisms of the second plurality of lenses and prisms comprise at least one forward prism away from the sensor and a plurality of rear prisms proximate the sensor, and at least one received image passes through every prism in the apparatus.
