Nikon HB-42 Bayonet Lens Hood for Nikon AF-S 60mm f/2.8G ED Macro Lens
Lens Hoods are primarily designed to prevent unwanted stray light from entering the lens creating lens flare and improving contrast and image quality. A hood also extends the length of the lens, assisting with keeping debris, moisture and dust away from your precious glass and protecting your lens from accidental impact damage.
