Abstract

An interchangeable lens includes: a mount on which a camera body can be mounted; a communication device that performs communication with the camera body; a driven member; a controller that controls the driven member; and a storage device that stores lens data related to control of the driven member by the controller. The controller sends to the camera body via the communication device lens-side judgment data based on the lens data and a parameter relating to the driven member received from the camera body via the communication device and based on which whether the lens data is considered to be properly stored in the storage device or not can be judged at the camera body.
