INTERCHANGEABLE LENS, CAMERA BODY, AND CAMERA SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an interchangeable lens, which a camera body can correctly control, when a moving image is captured, and to provide the camera body and a camera system. SOLUTION: The interchangeable lens (200) includes: a focus lens (230) for changing a focus state of an object image; a driving means (233) for driving the focus lens in the optical axial direction; a lens control means (240) for controlling the driving means so as to move the focus lens forward and backward along the optical axis at a predetermined drive frequency; and a storage means (242) for storing information for indicating that the driving means can move forward and backward along an optical axis.
