INTERCHANGEABLE LENS, CAMERA BODY, AND CAMERA SYSTEM

摘要

An interchangeable lens includes a drive unit (233) that drives a focus lens (230) back and forth along an optical axis, a storage unit (242) that stores driving method information indicating a driving method for autofocus control which is supported by the interchangeable lens, a sending unit (240) that sends the driving method information to the camera body, and a lens controller (240) that controls an operation of the interchangeable lens. A camera body (100, 140) determines control on the interchangeable lens by referring to the driving method information obtained from the interchangeable lens to generate a control signal. The lens controller (240) of the interchangeable lens controls the drive unit according to the driving method instructed by the control information received from the camera body, when autofocus control is performed.
