Petal shape avoids vignetting that can occur round lens hoods. Helps protect front of the lens scratches and dings while shooting. Deflects oblique light angles that often cause flare effects. Designed for the Nikon 18-70mm f3.5-4.5G ED IF AF-S DX Nikkor Zoom Lens. Petal-shaped lens hood.
The Nikon HB-32 Bayonet Lens Hood is a screw in lens hood for the Nikon 18-70mm, 18-135mm, 18-105mm, 18-140mm VR DX Nikkor Lenses. It is primarily designed to prevent unwanted stray light from entering the lens, and you also get the added benefit of some extra protection. The “petal” shape of this lens hood maximizes the amount of hood coverage for the minimum amount of weight and hood area.
