The Hoya Fusion One Next series complements the HOYA filter product line by merging all the highly regarded basic specifications, such as multi-layer coating, ultra-high light transmission, high quality optical glass and low profile frame, while newly incorporating a dirt and water repellent coating to meet the new standards in the photographic optical accessories industry. Recommended for both amateur and professional photographers. The Protector Filter is a popular addition to camera equipment as it protects the front element of the lens from scratches, dirt, water and other foreign objects. The 18-layer anti-reflective multi-layer coating is water and oil repellent, as well as scratch and dirt resistant. The ultra-thin frame is compatible with wide-angle lenses.
