This Underwater Red Glass Filter with Macro Lens Combo For GoPro HERO3 from Polar Pro is a dual purpose, underwater color-correction filter and macro lens combo designed to snap on to the GoPro HERO3 camera's waterproof housing. It features a red filter for color-correction in blue or tropical waters, and a macro lens that swings into place for obtaining close-up shots of fish, reefs, or other underwater subjects.
The red filter is constructed out of scratch-resistant glass for increased protection and maintained image sharpness. The filter balances out the strong blue cast that is caused by the water in order to provide vibrant, more natural-looking colors. The macro lens is made of strong optical acrylic, and allows you to get close-up shots by magnifying the center part of the frame. When attached, the macro lens allows your HERO3 to focus from 8 to 18 inches away underwater, and 3 to 12 inches away above water. The lens features a swinging design which lets you quickly swing and lock the macro lens in front of the filter, or lock it to the side of the camera when just the red filter is wanted. A tether cord and storage bag come included.
