A lens hood has a ring-shaped structure capable of mounting on a camera lens. Plastic plates are coupled to the ring-shaped lens hood to open or close the plastic plates by a control. Through the opening and closing, the lens hood can perform as a lens cap when the lens hood is closed, and can perform as a lens hood when the lens hood is opened, on the other hand, by being fixed due to a groove and a protrusion hung on an upper end of the plastic plate. |
