Tiffen Circular Polarizer Filter - 77mm

Tiffen Circular Polarizer Filters: Light rays that are reflected become polarised. Polarizing filters are used to control what light rays enter your camera lens. They can reduce undesirable reflections from non-metallic surfaces such as water or glass, and saturate colours to improve contrast. The effect can be seen in the viewfinder and adjusted by rotating the filter. The filter factor varies depending on how the filter is spun and oriented to the sun.
