The HB-117 Lens Hood is designed to protect the front element of the NIKKOR Z 24-70mm f/2.8 S II lens from glare and the elements while shooting. The HB-117 is a flower-shaped lens hood and features a filter adjustment window that can access a circular polarizer or other rotating filters without the need to remove the lens hood. The HB-117 can be mounted with the window on either the top or bottom for your convenience.
