Protect your camera lenses from dust， moisture， scratches， and other damage with this VILTROX NL-40.5mm Camera Lens Filter. It can effectively protect lens and absorb UV light. It is really an ideal neutral density filter which reduces and modifies intensity of all wavelengths or colors of light equally， giving no changes in hue of color rendition. It will eliminate UV problems from most situations where increased haze tends to wash out color and image clarity. Besides， it can be kept on your camera at all times.
