Absorbs the ultraviolet rays which often makes outdoor photographs hazy and indistinct. A muliti-purpose fine-weather filter for color as well as black and white films. Also serves as a permanent lens protector.

Filters are available in a number of series:

Standard: Mono-coated on both surfaces to reduce reflected light to around 4-5%.

HMC: Hoya Multi-Coated filters have 3 anti-reflected coatings on each surface which reduce reflected light to around 1-2%

Super HMC: Super coated Hoya filters have up to 12 anti-reflective coatings which reduce reflected light to around 0.3%

Ultra: Filters in this series use the new ULTRA thin rings which are designed primarily to avoid vignetting problems which occur with wide angle lenses. The ULTRA series filters use rings just 3mm in thickness. HMC Multicoating is applied to both sides of the filters and they are supplied with our push-on lens caps. This means that HOYA ULTRA series filters are the ultimate choice for wide angle lenses - there is no other filter available to exceed the ULTRA specification.
