The B+W 62mm Kaesemann High Transmission Circular Polarizer MRC Filter offers the same pictorial effect as linear polarizers, but with one major difference. As opposed to liner polarizers, the circular polarizer enables the use of auto focus and exposure settings without errors. The filter incorporates the latest Kaesemann HTC polarizing foils having high translucency with 99.5% transmission. The foils are placed between high-quality plano-parallel optical glass surfaces and precision-polished. Each glass surface layer has an anti-reflective coating to prevent internal ghosting and maintain optical fidelity and color tonality. The filter arranges polarized light in such a way that it is perpendicular to the reflected light, which allows for maximum absorption. As a result, photos have a noticeable increase in color saturation.
