ABSTRACT:
An interchangeable lens which can communicate with a camera body to which the interchangeable lens is detachably attached to exchange data of the interchangeable lens, includes a logic IC serving as an interface via which the interchangeable lens communicates with the camera body; a memory which is provided independent of the logic IC, connected to the logic IC, and stores the data of the interchangeable lens; and a controller, connected to the logic IC, for controlling operations of the interchangeable lens. The logic IC selectively switches connections of terminals thereof with the memory and the controller for communication therewith upon receiving a communication signal from the camera body.
