B&W 67 mm Circular Polarizer Multi-Coated (MC) Slim Glass filter - 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.
Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.
B&W slim filters are for wide-angle lenses and are 3mm thick. They do not have a front thread.
Note! Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems without problems).
