B+W circular for 49mm diameter C-POL Käsemann MRC Nano XS-Pro HTC

Create perfect pictures - the high-quality B+W Käsemann polarising filter easily filters out glare reflected by non-metallic objects, water, or glass. The filter makes the colours more bright and vivid, the sky bluer, and the white clouds fluffier and even more impressive! You can easily adjust the intensity of the effect by rotating the filter and changing the capture angle. The filter’s premium quality Schott optical glass is covered by fourteen anti-reflective layers on both sides, which effectively prevents unwanted glare and reflections, internal ghosting from the filter glass, and clears up haze on backlit photos. In addition, there is no colour shifting of the passing light. The protective Nano layers are extremely tough and provide excellent adhesion and scratch resistance. The filter features a full frontal thread that extends only about 4.2mm over the edge of the lens, and the polarising filter can also be used with wide-angle lenses. Thanks to its unique features, the filter is suitable not only for travel, but also for wet environments.

Perfect protection

The filter uses special Nano technology, which guarantees extreme protective layer hardness and excellent scratch resistance of the filter surface. The technology also provides great non-adherent properties, preventing dust and water from accumulating inside the filter. With these advanced Nano layers, even leaving a fingerprint is surprisingly difficult, as the filter remains perfectly clean. In addition, the highly efficient polarising foil is sealed with natural resin with high mould resistance. Combined with the black anti-reflective seal of the moisture filter edge, it makes the filter safe to use while travelling and in humid environments.

A detailed and sophisticated filter ring

The wonderfully sophisticated filter ring design provides a full frontal thread and the filter ring's outside diameter is slightly larger (by 4.2mm) than the actual thread size, surpassing the filters made by other manufacturers. The filter can even be used with extremely wide-angle lenses. The self-lubricating function of the filter ring ensures it remains tough and durable and rotates with exquisite smoothness. Schott's premium quality optical glass is positioned with perfect evenness in order to prevent deformations or material stress. All these features give the filter a long service life that will allow you to use the filter for many years.
