B+W circular 77mm diameter MRC

This high-quality, circular, thread-in polarizing filter is suitable for both digital and classic cameras. It is designed to operate in the toughest conditions, which was made possible due to its multi-layer coating that also offers maximum image quality.
The polarizing filter is used to suppress or remove glare from non-metallic surfaces such as water, glass, and the like, and serves as a camera front lens protection. It also slightly brightens the colours and improves the overall contrast of the image. For example, it is an ideal filter for shooting natural scenery, where it increases the beautiful contrast between blue sky and clouds. It's also suitable for taking pictures through glass and the like. The filter is grey, colour neutral - it lowers aperture (from 1 to 2) depending on the extent of polarization. The filter is circular, suitable for analogue and digital cameras and camcorders with autofocus (AF) or internal exposure meter (most of today's cameras and camcorders).
The filter is set in a rotating ring that can conveniently and easily adjust the direction of polarization.
