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 of long distances, particularly over water.
Ultra Violet filters are available in a variety of UV absorption levels. Helps protect your camera or camcorder lens against dust, moisture, fingerprints, scratches and damage. These filters can be kept on your lens at all times.
