Abstract
A camera includes a lens barrel including a rotary cylinder and a key cylinder movable forward relative to a barrel portion in a frame from a position radially inside the barrel portion, and a linearly movable cylinder movable forward relative to the rotary cylinder and the key cylinder from a position radially inside the key cylinder. The camera includes a light shield having a rear extendable portion connected to the frame and a front extendable portion connected to the linearly movable cylinder. The rear extendable portion contracts in an optical axis direction in a retracted state and extends in the optical axis direction in a first photographing state and a second photographing state. The front extendable portion contracts in the optical axis direction in the retracted state and extends to have a length greater than or equal to its equilibrium length in the optical axis direction in the second photographing state.
