B+W 1101635 82mm Master Kaesemann Circular Polarizer Filter

The B+W 1101635 82mm Master High Transmission Kaesemann Circular Polarizer represents the top tier of B+W's filter lineup. Built around Kaesemann polarizing film — which is sealed between two layers of optical glass to prevent moisture ingress and ensure uniform polarization across the entire surface — this filter delivers reliable performance in demanding shooting conditions. The high transmission design means it blocks less light than traditional polarizers, allowing you to maintain faster shutter speeds or lower ISOs while still achieving deep blue skies, reduced reflections on water and glass, and enhanced color saturation.

The MRC nano coating applied to the filter surfaces serves double duty: it minimizes internal reflections that cause flare and ghosting, and it creates a hydrophobic, oleophobic surface that repels water droplets, dust, and fingerprint oils. The black knurled thin profile mount provides a secure grip for rotation adjustments and is engineered to avoid vignetting on full-frame lenses as wide as 17mm. Whether you're shooting landscapes, architecture, or through windows, this filter is designed to integrate seamlessly into a professional workflow without compromising optical performance.
