Abstract: A lens hood device is provided for a zooms lens system for preventing light rays during the zooming operation (from any point outside the field angle of the zoom lens system) from coming into the focusing lens component thereof when varying the field angle. The lens hood comprises a lens hood ring which is moved along the optical axis relative to a fixed lens barrel in conjunction with movement during the zooming operation of a zoom lens component also along the optical axis relative to the fixed lens barrel. Also, the lens hood is capable of moving along the optical axis relative to the fixed lens barrel together with movement of the focusing lens along the optical axis relative to the fixed lens barrel during the focusing operation.
