A lens hood improves image quality by reducing flare, non-image forming light.

Slide the lens hood onto the bayonet mount at the end of the lens. Turn the hood clockwise until it clicks into place.

The hood can be reverse mounted for storage. The lens cap can be attached with the hood mounted.

Lens shadowing occurs when the lens or lens hood blocks part of the output from the built-in flash. Lens shadowing appears as a semi-circular shadow at the bottom (horizontal pictures) or side (vertical pictures) of the image. Remove the lens hood before using the built-in flash.

Lens shadowing may occur with the following lenses at the shorter focal lengths:

AF Zoom 28-70mm f/2.8G

AF Zoom 17-35mm f/3.5G

AF Zoom 28-135mm f/4.0-4.5

AF Zoom 28-85mm f/3.5-4.5

The built-in flash can not be used with the following lenses:

AF 300mm f/2.8 Apo G(HS)

AF 600mm f/4.0 Apo G(HS)

AF 300mm f/2.8 Apo G(D)SSM

Do not use the built-in or accessory flash when using a filter with a filter factor greater than 0, a close-up lens, or the focus-range limiter or macro release on certain lenses. This will result in an incorrect exposure.
