Hoya Hnano UV077 77mm HD Nano UV Filter

The Hoya HD Nano UV filter in 77mm is engineered to provide top-tier lens protection without compromising optical performance. At its core is chemically enhanced optical glass that Hoya rates as four times stronger than conventional filter glass, paired with a total of 32 layers of ultra-resistant nano coating applied to both sides of the element. This coating serves a dual purpose: it dramatically increases scratch resistance—up to 800% beyond standard multi-coated filters—and creates a surface that actively repels water, oil, and fingerprint smudges. In practical terms, this means the filter stays cleaner for longer and is far easier to wipe down in the field.

The extra-thin frame keeps the overall profile low to reduce the risk of vignetting, particularly useful when shooting at wider focal lengths. A front thread on the frame allows photographers to stack additional filters or attach a lens cap directly, maintaining full accessory compatibility. For photographers who keep a UV filter on their lens at all times for protection, the HD Nano series represents a meaningful upgrade over budget alternatives, delivering durability and clarity that justify the investment for anyone serious about keeping their optics in peak condition.
