Accessories-Lens Hoods
The use of a lens hood is recommended at all times to prevent extraneous light from striking the lens surface and causing flare or ghost, and as an added measure of protection against damage to the lens. Nikon lens hoods come in four types depending on the lens: Screw-In, Snap-On, Slip-On and Builtln. They are calculated precisely for each focal-length Nikkor lens to provide maximum protection against stray light.
To attach or remove the snap-on lens hood, simply depress the buttons on either side of the hood. It will also fit directly over a screw-in filter, so both can be used on a lens at the same time. When not in use, the snapon hood can be reversed for storage on the lens, and the lens and its hood can be stored together in the eveready case.
