Hoya Y5UV072 72mm HMC Haze UV Filter

The Hoya Y5UV072 is a 72mm UV filter from Hoya's HMC (Hoya Multi-Coating) line, designed to serve two purposes: absorbing ultraviolet light that can cause haze in outdoor photography, and providing a durable protective layer for your lens's front element. The filter's 12 layers of Super Multicoating are applied to both surfaces of the glass, reducing reflections to a minimum and achieving an average light transmission of 99.7%. This means the filter has virtually no measurable impact on exposure or image quality, making it practical to leave mounted on your lens at all times.

The slim 5mm ring profile is an important design consideration for photographers using wide-angle lenses, where thicker filter rings can intrude into the frame corners and cause vignetting. The Hoya HMC's low-profile aluminum ring threads smoothly onto any 72mm lens and adds minimal bulk or weight. While the UV-absorbing properties are most beneficial for film photographers shooting in high-altitude or coastal environments, digital shooters benefit from the scratch, dust, and moisture protection the filter provides—safeguarding an expensive front element with an inexpensive, easily replaceable piece of coated optical glass.
