The HB-69 Bayonet Lens Hood from Nikon is to be used with the NIKKOR 18 to 55 mm f/3.5 to 5.6G VR II lens. This lens accessory is primarily used to shield your shots from lens glare caused by stray light from the sun or other sources. It features a scalloped design that enables you to take wide angle shots. This design also helps reduce the vignetting caused when taking these shots. Apart from protecting your sensor from glare, this lens hood also protects the front end of your lens from bumps or accidental damage. It can be easily screwed on to the lens.
