The Nikon HB-74 lens hood is compatible with the AF-S NIKKOR 24-70mm f/2.8E ED VR lens. The lens hoods are mainly designed to prevent unwanted parasite light from entering the lens by extending the lens and shading it. A lens hood is designed to match the angle of the lens for which it is designed. Since the lens is extended with the use of the sunshade, the front lens is also protected from unwanted shocks.
