The Nikon HB-39 Bayonet Lens Hood is compatible with the AF-S DX NIKKOR 16-85mm f/3.5-5.6G ED VR lens and the AF-S DX NIKKOR 18-300mm f/3.5-6.3G ED VR lens. By reducing the amount of non-essential light falling onto the front lens element, lenses can better achieve their optimum optical performance, producing more saturated images.
