Dedicated to the Nikon AF-S NIKKOR 500mm f/4E FL ED VR and AF-S NIKKOR 500mm f/4G ED VR lenses, the HK-34 Lens Hood helps to minimize flare by deflecting stray light from entering the lens. Featuring a dedicated, slip-on design, the hood also provides additional protection to the lens from accidental impacts, bumps, or scratching. It is offered here as a spare or replacement for the hood originally included with the lens.
