Abstract: An imaging apparatus moves a lens in the optical axis direction with respect to the initialization position, and images a subject. The imaging apparatus includes a first lens, a second lens, a driving unit, a first position detection sensor, a second position detection sensor, a third position detection sensor, and a control unit. The driving unit moves the first lens and second lens in the optical axis direction. The first position detection sensor detects the position of the first lens. The second position detection sensor detects the position of the second lens. The third position detection sensor detects the position of the first lens and the position of the second lens. On the basis of the output from the third position detection sensor, the control unit executes the initializing processing of determining the initialization positions of the first lens and second lens.

Abstract: A lens barrel is detachably attached to a camera body, and includes an exterior unit, a rear frame, a tripod mount, and a tripod lock screw. The exterior unit includes an optical system. The rear frame is mounted to the exterior unit so as to be rotatable around an optical axis. An outer peripheral surface of the lens barrel is configured with the exterior unit and the rear frame. The tripod mount is provided on the rear frame to be fixed to a tripod. The tripod lock screw fixes a rotational position around the optical axis of the rear frame to the camera body at a predetermined rotational position, in a state in which the lens barrel is mounted to the camera body.
