INTERCHANGEABLE LENS, CAMERA BODY, AND CAMERA SYSTEM

摘要

An interchangeable lens (200) includes a focus lens (230) for changing a focus state of an object image, a driving unit (233) for driving the focus lens (230), a lens controller (240) for controlling the driving unit (233) so as to move the focus lens (230) forward and backward along the optical axis at a predetermined drive frequency, and a storage unit (242) for storing therein drive frequency information representing a drive frequency at which the driving unit can control. A camera body (100) obtains the drive frequency information from the interchangeable lens (200) and performs control while referring to the drive frequency information.
