Marumi 86mm UV Multi Coated Lens Protect Filter
Haze(UV) filters are wise initial investments. They 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. Haze-1 filters absorb approximately 71 percent of UV.
They are Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.
