HOYA Digital Kit UV PL ND8 Filters

UV Ultraviolet Filter:
UV-Ultraviolet filters are wise initial investments. They help protect your valuable investment from nicks,bumps,scratches and moisture, which can lead to costly repairs or render your lens permanently inoperable. Usually the filter is left on the lens at all times for protection. UV filters provide additional benefits of correction for Ultraviolet(UV) light which can register on film or digital media as a bluish cast and can obscure distant details. 

Circular Polarizer/Glare Reduction Filter:
Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated.
