Circular polarizing filters zero in on which light rays enter your cameras lens. They then 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 the LCD screen and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. Circular polarizing filters do not affect the overall color balance of a shot. Includes a 1 Year Warranty.
