Hoya makes a number of popular camera lens filters.
"HMC" stands for the Hoya Multi-Coating (triply-layered) that many of the company's premium photographic filters are treated with. Established in Japan in 1941, Hoya quickly became a respected manufacturer of optical glass accessories. Hoya's product line is vast and varied, ranging from standard ultraviolet (UV) filters to fancy special effects filters. HMC filters are among the most popular items offered by the company as they render reflections and lens flare nearly undetectable.
Instructions
1. Remove the cap or hood from your camera's lens.
2. Locate the filter, which is screwed onto the front of the lens. If the filter is stored in a pouch or plastic container, remove it.
3. Look closely at the small print on the edges of the filter. Hoya's multi-coated filters will read "HOYA SUPER HMC" or "HOYA HMC." Following this script will be the filter's thread size, such as 72mm, and type, such as UV.
4. Hold the lens at an angle so you can see a reflection on the surface of the filter. If the reflection is tinted green, your lens is affixed with an HMC filter. This step can be used if the script on the filter's edge is illegible or has been rubbed off.
