Bayonet lens hood. Minimizes stray light, and reduces lens flare and ghosting. The hood can be reversed and mounted on the lens when not in use. Twist-lock mounting for extra security.

This lens shade is an 'inny' rather than the standard 'outy'..meaning it is narrower on the outer edge than on the edge that screws onto the lens. I guess it works, but it also means you cannot use any lens cap with it which just makes no sense to me.
