Haze(UV) filters are wise initial investments. The Nikon 82mm UV Haze L37C Glass Filter will help protect your valuable investment from dust, moisture and scratches, which can lead to costly repairs. If desired they can be left on the lens at all times for protection. Haze filters provide additional benefits of correction for Ultraviolet(UV) light which can register on film and videotape as a bluish cast and can obscure distant details. Ultraviolet filters allow you to correct for the UV effect to varying degrees. The UV-Haze filter is helpful when photographing mountain and marine scenes, where increased haze threatens to make your photographs indistinct in color and clarity. Nikons integrated multicoating minimizes reflection at the filter surfaces which reduces flare and ghosting.
