Vivitar 800mm F/11 Series 1 Catadioptric Mirror Manual Focus Lens For Nikon {35.5} Description


Vivitar 800mm f/11 Solid Catadioptric lens is a solid glass design, with no air spaces between the front lens, rear mirror and front reflector. The 800mm f/11 Solid Catadioptric was created for the U.S. Military by Perkin-Elmer. 

This is a single-element lens that will not lose collimation when dropped or banged against a hard surface, thus causing the mirrors to change angle in relation to others. It weighs less than 3lbs and longer than 3 inches long. It has a rugged design with a metal lens barrel. The lens is extremely short compared to the effective focal length of 800mm. The lens may be the shortest lens created.
