Fotodiox Filter-CPL-77mm 77 mm Circular Polarizer Filter

This filter from Fotodiox is a double threaded circular polarizer (CPL) filter made of optical glass and featuring a rotating ring to allow for light ray selection. Remove unwanted reflections from non-metallic surfaces such as water or glass. CPL Filters are used to select which light rays enter your camera lens. CPL filters can also be used to saturate colors and to provide better contrast. The effect can be seen through the cameras viewfinder and changed by rotating the filter ring. The filter factor varies according to how the filter is rotated and its orientation to the sun or light source(approx. +1.3 stops). Typical applications include darkening skies, water reflection elimination and window& glass & eyeglass reflection elimination.
