A Lens Hood helps maintain impressive image quality by reducing lens flare and ghosting caused by stray light entering the lens. The threaded front allows you to attach different filters to your lens, meaning you can tailor your pictures to suit you. Additionally, a dark matte interior prevents unwanted reflections from affecting your photos. This lens hood provides some protection from knocks and scrapes.
