A camera body 3 includes a cross control key 27 and a body microcomputer 10. The body microcomputer 10 can acquire lens information related to an interchangeable lens unit 2 from the interchangeable lens unit 2. The body microcomputer 10 decides whether or not the interchangeable lens unit 2 is compatible with electric zoom on the basis of lens information. The body microcomputer 10 also activates zoom operation at the cross control key 27 on the basis of this decision result.
