description The invention speeds up operation of an interchangeable lens. The interchangeable lens, which is removably mounted on a camera body, includes a communication control microcomputer, a lens driving circuit and a lens driving actuator. A body-side microcomputer and the communication control microcomputer of the interchangeable lens are connected and are capable of communicating with each other. Lines are provided in such a manner that the lens driving circuit and body-side microcomputer can communicate directly. A command from the body-side microcomputer is input to the lens driving circuit. This allows the lens driving circuit to be controlled directly and makes it possible to control the interchangeable lens at high speed.
