The HB-64 Bayonet lens hood from Nikon is designed to prevent flares and stray light from hitting the lens elements. This hood has a flower shaped design that helps avoid stray light from entering the lens, giving you brighter color and contrast. Its hard plastic body also protects the lens from minor external impacts, thereby protecting the lens. The matte black interior absorbs light and reduces reflections. This lens hood has a diameter of 67 mm and fits easily onto a lens filter of the same size.
