An interchangeable lens includes an obtaining unit for obtaining first control information and second control information from the camera body, the first control information being an instruction to control the first drive unit (diaphragm), the second control information being an instruction to control the second drive unit (focus lens, etc), a storage unit for storing the obtained second control information, and a controller for controlling the first drive unit and the second drive unit based on the first and second control information obtained. The second control information (reservation control information) is an instruction to control the second drive unit when the obtaining unit receives the first control information after receiving the second control information. When the obtaining unit obtains the first control information after obtaining the second control information, the controller drives the first drive unit and the second drive unit in parallel based on the obtained first control information and the stored second control information.
