Hoya Hnano UV072 72mm HD Nano UV Filter

The Hoya HD Nano UV filter represents the top tier of Hoya's protective filter lineup, engineered for photographers who want the highest level of lens protection without any compromise in image quality. The filter's defining feature is its 32-layer nano coating — 16 layers on each side of the optical glass — which serves multiple purposes: it maximizes light transmission to near-perfect levels, virtually eliminates reflections and ghosting, and creates an ultra-smooth surface that actively repels water, oil, grease, and fingerprints. This means the filter stays cleaner in the field and wipes clean far more easily than conventional coated filters.

Durability is where the HD Nano truly distinguishes itself. Hoya's nano coating process bonds high-density nanoparticles to the glass surface, resulting in a filter that is 800% more scratch-resistant than standard multi-coated filters and four times harder than chemically strengthened optical glass. For photographers who keep a UV filter permanently mounted for lens protection, this level of resilience means the HD Nano can withstand years of daily use, accidental contact, and field cleaning without developing the micro-scratches that gradually degrade image quality on lesser filters. The 72mm filter features an extra-fine aluminum mount that keeps the profile slim to reduce vignetting risk, and includes front threads for attaching lens caps or stacking additional filters when needed.
