Formatt Hitech 82mm Hi Def Circular Schott-Desag B270 Crown Optical Glass Polarizer

The Formatt 82mm Circular Schott-Desag B270 Crown Optical Glass Polarizer - Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast.

The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.

Due to the sharpness of HD cameras and lenses, certain filters come in handy to assist in flattering your subject. This incredible technological breakthrough gives HD shooters the extra touch of clarity they want.

Formatt's Crown Polarizer enables you to achieve a level of optical performance previously unavailable. The polarizing film is fabricated between two pieces of Formatt's crystal clear white water optical glass. The absolute clarity of the glass combined with advanced polarizing material make crown Polarizing filters particularly effective on demanding scenes.
