Overview

The Hoya Fusion One UV filter in 43mm is built for photographers who want reliable lens protection without sacrificing image clarity. Its 18 layers of multi-coating are applied to both sides of the glass, working to maximize light transmission while minimizing reflections, ghosting, and flare. The result is a filter that can stay on your lens full-time as a protective barrier against dust, moisture, fingerprints, and accidental contact — all without introducing noticeable degradation to your images.

A key feature of the Fusion One line is its water and stain-repellent coating. Water beads up and rolls off the surface rather than clinging, and oily fingerprints wipe away more easily than on uncoated filters. The one-piece aluminum frame is both lightweight and durable, and it includes a front thread so you can attach a lens cap or stack another filter on top. For 43mm lens owners looking for a set-it-and-forget-it protective filter from a trusted optical brand, the Hoya Fusion One UV is a strong everyday choice.

Pros & Cons

👍 Pros

18 layers of multi-coating deliver high light transmission with minimal flare and ghosting.

Provides constant physical protection for the front element of your lens against scratches and impacts.

Higher price point than basic uncoated UV filters in the same size.
