Schneider 800mm F12 Apo-Tele-Xenar HM - Copal 3 | $8215.95 | | |
The Apo-Tele-Xenar is a 5-element telephoto lens system with an angle of view of 35 degrees, which can be used with a focal length of 400mm for formats of up to 5x7" and with a focal length of 800mm for formats of up to 8x10". The apochromatic correction,
achieved by the use of special optical glass, gives a clear reduction in the secondary spectrum. The resolution of these special lenses is not sensitive at the normal working aperture to changes in the object to image ratio, with the result that the Apo-
Tele-Xenar 5.6/400mm can be used without hesitation at a range of 2 meters. To avoid reflections and to improve transmission the Apo-Tele-Xenar has a multi-layer anti-reflection coating.
Features- Only 585mm(23.6") extension needed for infinity focus
- Apo-chromatic design
