The Carl Zeiss Mirotar 500 mm f/ 8 C/Y is a high quality mirror lens for the 35 mm C/Y SLR cameras. Due to its construction with additional mirrors, it is practically devoid of chromatic aberrations.
The scheme of mirror lenses was borrowed from that of telescopes, where it enables to increase focal length without increasing telescope dimensions.
The aperture values of the Carl Zeiss Mirotar 500 mm f/ 8 lens can be changed by installing special dark filters between the camera the rear lens.
