Abstract:
An interchangeable lens to be removably attached to a camera body, includes: a receiving device that receives predetermined control data from the camera body through a first transmission path; a control device that executes predetermined control processing based upon the control data upon reception of the control data by the receiving device; a generation device that executes at predetermined intervals generation processing for generating predetermined lens data which indicates an operating state of the interchangeable lens; a transmission device that transmits the lens data to the camera body through a second transmission path, which is different from the first transmission path, upon generation of the lens data by the generation device; and a prioritizing device that gives priority to the generation processing by the generation device over the control processing by the control device.
