Carl Zeiss Mirotar 500 mm f/ 8 C/Y Lens Volantino

Mirotar

f/5.6 - 1000 mm

The basic design of the Mirotar

lens - concave primary

mirror with a hole in the center and convex secondary

mirror - is similar to the design frequently applied in

astronomical telescopes. It further contains two lens

elements in front of and two behind the mirror surfaces.

They reduce the aberrations caused by the mirror to a

minimum.
Whereas conventional lenses with a long focal length

and apertures larger than f/8 exhibit disturbing

chromatic aberrations, these are completely eliminated

when mirrors are used. The elements employed for

correction in the mirror lens are of low refractive power

and are chromatically corrected so that the

focus is maintained over the entire photographic

spectrum. Even in IR photography, the focus is retained

once it has been set visually.

The very high uniform image quality of the Mirotar

lens is due not only to the extremely good overall

correction, but also to the meticulous care taken in the

production of the mirror and lens systems, the mounts

and in the assembly of the lens. Distant objects are

imaged with keen definition in every detail. Pictures
taken with the Mirotar

lens thus permit considerable

subsequent enlargement. The high speed permits press

and wildlife photography even under unfavorable

lighting conditions.
