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.

Looked around and this was the best deal on this product at the time. A well-made filter at a good price. Used to protect the lens and retractable cover on my Canon HD video camera (had a repair shortly after receiving it due to debris in the lens area not allowing the cover to close).
