摘要：
An interchangeable lens (200) has a focus lens (230) for changing focus conditions of an object image, a drive means (233) for driving the focus lens (230), a lens control means (240) for controlling the drive means (233) so as to advance and retract the focus lens (230) along the optical axis at a predetermined drive frequency, and a memory means (242) for storing therein drive frequency information representing a drive frequency which can be controlled by the drive means. A camera body (100) obtains the drive frequency information from the interchangeable lens (200) and performs control while referring to the drive frequency information.
