B+W 58mm MASTER High Transmission Circular Polarizer MRC Nano Filter

The B+W 58mm MASTER High Transmission Circular Polarizer MRC Nano Filter is a circular polarizing filter that reduces reflections from non-metallic surfaces such as water, glass, and glossy paint. Objects and people behind surfaces such as shop windows and car windshields become visible without image processing. B+W polarizing filters augment the purity of the intrinsic colors and increase color saturation. This filter is often regarded as the most important filter for photography.Because the filter mounts rotate, the polarization effect can be visibly controlled in the viewfinder or on the monitor display. The B+W circular polarizer is compatible with nearly all modern cameras when beam splitters are used in the light path for TTL exposure metering or autofocus. Exposure errors are therefore avoided. The multiplying factor with HTC is 2 to 3, which is equivalent to 1 to 1.5 f-stops. Other polarizers up to approx. 3 stops. MRC Nano coated glass is used as the basis for the new Master
