B+W BW7227952mm 092 Uncoated IR Dark Red Filter - F-PRO Mount
Opis:
Manufacturer's Description
The B+W 092 has become a popular filter for IR photography with digital SLR cameras. This nearly opaque filter looks dark purplish when held in front of a light source and blocks the visible spectrum up to 650 nm. It passes only 50% of the radiation just below 700 nm and from 730 nm to 2000 nm, transmission is greater than 90%. As the sensitization of IR films barely extends beyond 1000 nm, the red portion that is transmitted still makes a relevant contribution to the exposure. Effectiveness and filter factor are largely film and light dependent and individual testing is recommended. B+W filters are made with Schott glass which guarantees the very highest glass quality. Good quality cameras and lenses are a major investment and at B+W we believe that if you should have the best quality filters. There’s no point in buying an expensive, optically superior lens, only to put a piece of inferior glass over the front of it! B+W filters all feature brass mounts, designed to fix the high-quality filter glass in position “for life”. Brass mounts won’t bind with your lens thread, or other filters – a major advantage over cheaper filters.
