The Haze UV (0) is a multi-coated filter by Hoya, that reduces UV light. I believe it absorbs 39% of Ultra Violet light, the same as their Pro-1 Digital series. There are a vareity of Haze and UV protection filters available. Tiffen makes UV and Haze filters that absorb anywhere from15% to nearly 100% of UV light and our multi-coated Digital HT Haze 86 absorbs 86% of UV light, so there is a variety to choose from. There is something available to fit any budget.
