Abstract
An object of the invention is to provide a camera body of which a manual focus mode can be easily switched.A lens barrel includes an imaging optical system, a first operation ring, a second operation ring, and first and second sensors. The first sensor detects the rotation of the first operation ring and the rotation angle and the rotational direction of the first operation ring. The second sensor detects the angular position of the second operation ring. The imaging optical system includes a focus lens. A camera body includes a body control unit. The body control unit selectively executes a first manual focus mode in which the focus lens is moved according to the rotational direction and the rotation angle detected by the first sensor and a second manual focus mode in which the focus lens is moved according to the angular position detected by the second sensor.
