Safeguard your lens and absorb UV light. Film and video are more sensitive to UV light than our eyes are. This often shows up as a bluish cast in images, especially shots from high altitudes and long distances, particularly over water. Ultra Violet filters are available in a variety of UV absorption levels.
Note! Tiffen wide-angle filters have low profile rings to prevent vignetting which can occur when using standard filters on ultra wide angle lenses. They do not have a front thread, and can not accept standard snap on lens caps

the filter had an insert that prevented me from placing another filter over it and prevented the lens cap from going on I removed it not knowing that it was all that held in the glass. The filter fell out and broke. I am not sure why it was constructed this way since the standard nikon lens cap will not go on the lens with the filter on.
