B+W Circular Polarizer Filter Circular Polarizing Filter Schott optical glass Brass holder with a front thread for additional accessories Durable Resistant to moisture, dust, dirt and scratches Easy to clean The polarizing filter allows you to remove glare from non-metallic surfaces such as water, glass, etc. It also increases the intensity of colors - they become cleaner and have greater contrast, which allows you to darken the sky and emphasize white clouds against it. The rotatable holder of polarizing filters allows you to choose the optimal effect. It can be observed in the viewfinder of an SLR camera. When using with other filters, it is recommended to attach them first from the side of the frame. B + W filters are made of the highest quality Schott optical glass, characterized by high homogeneity and cohesiveness. Filters are cut with diamond blades from glass cylinders, then each filter is carefully polished, smoothed and subjected to a series of tests. First of all, its thickness, flatness and repeatability of results are checked.B + W filter holders are made of brass. Brass is a more durable material than aluminum, it is also more resistant to temperature changes, thanks to which the housings do not jam in the heat.The B + W company, operating on the photographic market since 1947, guarantees the highest level of quality of its products. Using the latest technologies in the production of filters, it is a symbol of the highest optical and mechanical quality.
