Hoya HFOPR043 Fusion One 43mm Lens Protector Filter

The Hoya Fusion One Protector Filter in 43mm is built to serve a single purpose exceptionally well: keeping your front lens element safe from scratches, dust, moisture, and accidental contact without introducing any optical penalty. Hoya achieves this through 18 layers of precision multi-coating applied to superior optical glass, resulting in a filter with high light transmission and low reflectance. The coating also provides a water and stain repellent surface, so rain droplets bead up and roll off while fingerprints and smudges wipe away easily — a practical advantage when shooting in the field.

Designed for permanent installation on lenses with a 43mm filter thread, the Fusion One Protector adds a physical barrier between the environment and your lens without affecting image sharpness, contrast, or color fidelity. It is far less expensive to replace a scratched filter than to repair or replace a damaged front element, making this filter a straightforward investment in protecting your glass. The slim ring design keeps the profile low to minimize any risk of vignetting, and the overall build quality reflects Hoya's reputation as one of the leading optical filter manufacturers in the industry.
