HilexiOne in the name of this series is a legacy of the PRO1D series, in memory of its contribution to the creativity of photographers, with the belief that this new series will serve them just as well for many decades to come.

The FusionOne series belongs to HOYA's filter lines, utilizing all the essential high-performance specifications, such as multi-coating, extremely high light transmission, high-quality optical glass, a low-profile frame, and a water-repellent coating to match the new standards of the photographic optics components industry.

The protection filters (Protector) of this series feature all these characteristics while simultaneously having no effect on the color balance of your lenses. They are recommended for both amateur and professional photographers.
