K&F Concept UV filters provide essential protection for lenses against dirt, scratches, fingerprints and accidental impacts.

By reducing ultraviolet (UV) light, they improve contrast and minimize blur in video and digital photography. The filters, made of premium quality Japanese optical glass, are 4x stronger and have a 28-layer NANOTEC coating, which is hydrophobic, scratch-resistant and provides 99.6% light transmission. The thin 3.3 mm frame does not cause vignetting even when using telephoto lenses. Before you buy, you should make sure that you have checked the camera's lens length, which is usually marked with a "?" (diameter) symbol. For example, ?67 according to the 67mm lens thread.
