B+W 67E Slim Circular Polariser MRC
Product code: 67CPLSLIM
- 1 Year Warrnaty
B+W Polarizers increase color saturation and reduce reflections, circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings with modern automatic cameras.The individually selected “high-end” polarizing foils of the Käsemann-type filters are neutral in color, have a higher efficiency than conventional polarizing foils. They are cemented between high-grade plano-parallel optical glass, the resulting sandwich is then precision-polished again to achieve highly accurate plano-parallel surfaces. Subsequently they are edge-sealed to protect the foil against humidity and extremes of temperature. Brass mounts made on CNC-controlled machines ensure precise seating on the lens. 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”. The slim mount is less than half the height of a standard filter ring so can be used with wide angle lenses without any danger of causing a vingette. Brass mounts won’t bind with your lens thread, or other filters – a major advantage over cheaper filters. The MRC (Multi-Resistant Coating) by B+W is not only an extraordinarily effective multiple layer coating, it is also harder than glass, so that it protects filters from scratches (for instance when cleaning the filters), and it is also water and dirt repellent.
