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.

Abstract: A lens apparatus includes a tripod mount, a cylindrical member supported rotatably around an optical axis on the tripod mount, a roller housed in the tripod mount and including a rolling bearing and a shaft member engaged with the rolling bearing, a roller holding member configured to rotatably hold the roller, and a biasing member configured to bias the roller against the cylindrical member via the roller holding member.

Abstract: A panoramic camera has an objective drum, an electric motor which drives the objective drum and has a motor shaft, the electric motor being arranged axis-parallel to and at a distance from the objective drum and having a regulatable speed, a plurality of outputs having different speeds and connected with the motor shaft, and a plurality of intermediate outputs connecting the outputs selectively with the objective drum.
