Nikon 67MM CIRCULAR POLARIZER II (2255) Product Details
Light rays which are reflected become polarized, and 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. Filter factor is between 2.3 and 2.8 (approx. +1.3 stops). Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems). The "II" polarizing filters are now made especially thin and can be used with wide-angle lenses. Dedicated bayonet hoods can also be used.
