Carl Zeiss Mirotar 500 mm f/ 8 C/Y Lens Folleto
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
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
taken with the Mirotar
®
lens thus permit considerable
subsequent enlargement. The high speed permits press
and wildlife photography even under unfavorable
lighting conditions.
