The B+W filters are made from a brass alloy with excellent physical characteristics and a high purity, distorted, thick Schott glass, especially precise elaboration, state -of -the -art production technology, according to the highest quality requirements. Finally, with different surface treatment, they provide each type to complete the perfection of the B+W filters. From the raw materials used to the final smoothing, 100% "Made in Germany". The B+W High Transmission Käemann Circular Polar Films (Factory Code: AUC) radically reduce reflection and increase the color saturation of the image. The polar filter is an almost indispensable supplies for photography outdoors. To control its optimum performance, the filter must be adjusted by rotating the outer part. You can check the right position in the search image. When using the natural blue of the sky, the white cloud ruffles become visible. By excluding the reflection of the water surface or glass surfaces, the content behind them also becomes photograpable. High Transmission polar filters cause 1 FE less light loss than other models. This is a huge advantage, a larger freedom factor for the photographer. Käsemann manufacturing technology is a perfect quality in making polar filters. When making these filters, the highest quality polar foil is used, which is incorporated in a perfectly flat position between the glass sheets, and then glued to the "sandwich" and with a matte painting. Inside the filter, dirt between the glass sheets, in mist can no longer enter. This filter is provided with eight layers of surface treatment on both sides, which provide, among other things, reflection and dirt resistance. In addition, it has received a NANO coating that has a moisture repellent effect and makes cleaning very easier. This filter is made with an XS-Pro slot, which is excellent for thinned, high-angle lenses. It is also equipped with a front -side thread, so additional filter (eg CPL) or accessory can be connected, and internal lens caps can be used.
