  • Patent number: 11921405
    Abstract: A camera can perform two different photographing operations with a lens at different positions without vignetting while preventing entry of light and dust. A camera includes a frame including a film compartment to contain a photographic film and a barrel extending from the film compartment in an optical axis direction, and a lens barrel movable in the barrel in X-direction. The lens barrel includes cylinders movable frontward relative to the barrel, and a cylinder movable frontward relative to the cylinder. The camera includes a rear bellows connecting the frame and the cylinder, and a front bellows connecting the cylinder and the cylinder. In a first photographing state in which the cylinders extend frontward relative to the barrel and the cylinder is accommodated inside the cylinder, the rear bellows is expanded and the front bellows is partially contracted. In a second photographing state, the cylinder extends frontward relative to the cylinder.
