Hoya YYU4152 HD Nano MkII UV Filter 52mm

The Hoya HD Nano Mk II UV Filter in 52mm brings top-tier lens protection to any compatible lens without compromising optical performance. At its core is High Density Sharp Cut UV glass that effectively blocks ultraviolet light to reduce haze and protect your front lens element from dust, moisture, and accidental contact. The defining feature is Hoya's new 32-layer nano coating applied to both sides of the glass, engineered to be 800% more scratch resistant than standard multi-coatings. This means the filter surface holds up significantly better against everyday wear, cleaning, and incidental abrasion over time.

Beyond durability, the coating is designed to be stain resistant with water and oil repellent properties, so fingerprints, rain drops, and smudges wipe away quickly with a dry cloth. The very thin filter frame keeps the overall profile low to help avoid vignetting, especially on wider focal lengths, while retaining front threads for attaching lens caps or stacking additional filters when needed. For photographers who keep a UV filter on their lens as everyday protection, the Hoya HD Nano Mk II represents a meaningful upgrade in both resilience and ease of maintenance over standard or first-generation HD filters.
