The Hoya 72mm HD Digital UV Filter is a multi-purpose fine-weather filter that absorbs the ultraviolet rays which often make outdoor photographs hazy and indistinct. A multi-purpose, fine-weather filter for colour as well as black and white films, the Hoya 72mm HD Digital UV Filter also serves as a permanent lens protector. Made from High Density Sharp Cut UV Glass and chemically enhanced optical glass, the Hoya Digital UV filter is four times stronger than a regular filter. It also has a 8-layer Anti-Reflective Multi-Coating and is water & oil repellent, scratch & stain resistant.
