With circular polarizing filters, photographers can achieve creative, in-camera effects that are no longer possible after the image is captured. A polarizing filter eliminates unwanted reflections from non-metallic surfaces such as water or glass, as well as light that reflects moisture and pollutants in the atmosphere. HOYA FUSION ONE is a new filter series based on the latest optical HOYA technology. It replaces the successful long-selling series HOYA PRO1 Digital, which has been widely used by amateur and professional photographers around the world. HOYA FUSION ONE enhances the HOYA filter product line by merging all highly valued base specifications, such as multi-layer coating, ultra-high light transmission, high-quality optical glass, and low-profile frames, while also incorporating a dirt and water-repellent coating to meet the new industry standards for photographic optical accessories.
