The Hoya 77mm 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 77mm 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.
