Hoya manufactures a full line of filters in both standard and Hoya multi-coated. The difference between Hoya's standard line and that of other manufacturers is that Hoya standard filters have one layer of anti-reflective coating applied to each surface of the glass. To provide photographers with a higher quality professionals require, Hoya created the Multi-coated line of filters.
