The HD Mk II UV is the ultimate protection for your front-lens element against scratches, dirt and bumps. The great addition compared to a regular protector is that the filter also perfectly cuts out UV light, reducing the haze and blue color cast which can be caused by it in certain settings, giving you ultimately a sharper image.
The HOYA HD Mk II UV is equipped with a special chemically enhanced optical glass that is four-times stronger than normal glass, providing a superior level of protection.
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.
