Nikon CPL-3L Insteekfilter Circulair Pola

Dramatically reduces reflections from water and glass as well as rendering blue skies darker. Designed for use with telephoto lenses that provide a slip-in filter holder, these filters reduce glare from non-metallic surfaces such as glass and water. These filters do not affect autofocus or auto exposure operation. Converts the bayonet mount of reverse-mounted lenses to the 52mm thread used for filters and hoods. Simply turn the rotating ring on the holder to find the most effective position. Both the C-PL1L and C-PL3L feature a diameter of 52 mm.
