Overview

The Hoya Fusion ONE Protector Filter in 37mm is engineered to provide constant, transparent protection for your lens's front element. Built with Hoya's professional-grade optical glass, the filter is designed to be optically neutral — it does not introduce color shifts, softness, or distortion. What sets the Fusion ONE apart from basic protector filters is its 18-layer Super HMC (Hoya Multi-Coating) treatment, which maximizes light transmission while minimizing ghosting and flare, even when shooting toward bright light sources.

The filter's surface features water-repellent and stain-resistant coatings that cause moisture to bead up and roll off and make fingerprints and smudges easy to wipe clean with a soft cloth. This combination of optical performance and practical convenience makes the Fusion ONE suitable for permanent attachment to your lens, serving as a durable first line of defense against scratches, dust, and accidental impacts. The low-profile filter frame keeps the overall stack height minimal, reducing the likelihood of vignetting — a particularly important consideration at this 37mm size, which is commonly found on compact and wide-angle lenses.
