HOYA UV HD Mk II 82mm

HOYA UV HD MK II 82MM

UV filter with chemically reinforced optical glass.
Its sharp UV cut property cuts out the UV light while not having any negative effect on the colors in the visible light spectrum, so there will never be an unwanted change of colors in your image. As UV light can potentially cause a haze and blue color cast under certain conditions, the filter will reduce such negative effects which will make your final image ultimately sharper and clearer.
Also serves as a permanent lens protector.
