Schneider Kreuznach CCTV High Resolution, IR compensated, 4.8mm / F1.8 (400-1000nm multispectral design)
- Description: This 2/3" C-Mount lens is a high end CCTV lens very much used in highly demanding environment of high resolution CCTV and industrial/cine work. Contrast and resolution are no-compomise. This lens works perfect. Iris operation has been modified so that you get to it DC 1-6V DC current to close or open (reversing polarity). It is sold with it opened (unlike many CCTV lenses, diaphragm it remains in the place you leave it). It has quality manual focus ring which extends beyond the normal focus range found in C mount lenses. It will produce some vignetting in 4/3 detectors, but very little. Includes both hard (back) and front (soft) original caps.
- More info: They are designed for high resolution work (contrast is just amazing) and for a spectral range of 400-1000 nm (IR compensated), which means it can be used in the visible and near infrared range, practically without focus difference. The high optical performance is achieved by a sophisticated optical design and the use of ultra low dispersion glass. A special broadband coating reduces stray light and increases transmission over the whole spectral range. In my tests with slanted edge method, these Schneider Cinegon/Xenoplan broadband lenses are among the top winners always. Original cost about 1700€. Very high end glass!
- Issues: none
