ABSTRACT:
An interchangeable lens which is mountable to a camera body and operates according to a command from the camera body includes a diaphragm operable to regulate an amount of light from a subject by changing an aperture, a drive unit operable to change the aperture of the diaphragm, and a lens controller operable to control the drive unit to change the aperture of the diaphragm according to an instruction received from the camera body. When the lens controller receives a new instruction from the camera body while changing the aperture of the diaphragm, the lens controller controls the drive unit to change the aperture of the diaphragm based on the new instruction without waiting for completion of the change of the aperture according to a previous instruction.
