Overview

The Hoya Fusion One UV Filter in 46mm is a premium lens filter built around high-quality optical glass and an 18-layer multi-coating system. This coating architecture serves multiple purposes: it maximizes light transmission so the filter has minimal impact on exposure and image sharpness, it reduces flare and ghosting caused by stray light, and it provides a water and stain-repellent surface that causes moisture to bead off and makes fingerprints and smudges easy to wipe away.

The filter is built on a one-piece ultra-thin frame that reduces the risk of vignetting on wide-angle lenses while including front threads for stacking additional filters when needed. As a UV filter, it blocks ultraviolet light that can introduce haze into images, particularly in outdoor and high-altitude shooting conditions. Many photographers use this filter as permanent front-element protection, keeping it mounted on the lens to guard against scratches, dust, and moisture while maintaining the optical performance expected from the Hoya Fusion One series.
