Zeikos 82mm Lens Protection Protect your camera lens from dirt, dust, moisture, scratches, fingerprints, accidental knocks, and other damage. Designed for general use, the filter offers convenient everyday protection and can remain on the camera at all times. UV Light Reduction UV light can negatively affect images, creating a bluish cast on color film or a low-contrast haze on either color or black and white. These negative effects of UV light are particularly noticeable with outdoor photographs, especially when taken at high altitudes or over long distances. The UV protection filter helps absorb ultraviolet light, which in turn helps create clearer, more accurately vibrant photographs.
