Absorbs UV rays, resulting in clearer, sharper images and reduced haze. Prevents unwanted reflections and increases light transmission. Repels water droplets, making cleaning of the filter surface easier. Prevents vignetting on wide-angle lenses, even when a lens cap is on. If the filter stays on the lens, it serves as everyday lens protection. Maintains neutral color balance in bright light at slow shutter speeds and reduces unwanted lens flare. Perfect for shooting long exposures of clouds, oceans and rivers, waterfalls, landscapes, light trails, creative portraits and more. Slim minimal design for an easy travel companion. Laser-etched markings on the edge of the neutral density filter eliminate guesswork of light intake during run-and-gun shooting. This filter is quick and easy to mount, small and light. All you need for use is your camera and the lens.
