Abstract
To provide an interchangeable lens, a camera system, a communication method, and a program in which lens data can be caused to be efficiently stored in an interchangeable lens, necessity of storing the lens data in the accessory can be eliminated by storing lens data in a case where an accessory is not mounted on the interchangeable lens and lens data in a case where the accessory is mounted on the interchangeable lens, and it is unnecessary to have a particular function of transmitting appropriate lens data to the accessory. An interchangeable lens includes a specifying unit that specifies a mounted accessory by acquiring identification information from the accessory, a storage unit including a first storage area that stores first lens data and a second storage area that stores one or a plurality of pieces of second lens data, a third lens data generation unit, and a lens control unit.
