Ultraviolet and Circular Polarizing filtersTwo Adapter Rings for GoPro and Carrying Case1-Year Manufacturer Limited Warranty5-Piece Filter Kit for GoPro Hero 3+Product Description: The 5-Piece Filter and Adapter Kit for GoPro action cameras provides users with an extensive assortment of important optical accessories that will both protect your camera and improve upon your photo and video capture. The UV (ultraviolet) filter serves a dual purpose, it absorbs UV light and reduce the bluish hue of daylight, while protecting your lens from external debris. The CPL (circular polarizing) filter helps by filtering out polarized light, created by non-metallic surfaces (open water, glass windows, etc.). Each filter snaps on easily and securely to your GoPro camera. The kit also includes two specialized adapters for GoPro 3 and 3+ cameras that mount directly to the body and onto the standard GoPro housing, as well as a convenient carrying case.
