More Information
Summary:The invention provides an interchangeable lens capable of performing a normal communication even though processes for respectively controlling two transmission paths are simultaneously performed. The interchangeable lens to be removably attached to a camera body, includes: a lens side first communication circuit (212) for receiving a preset control data from the camera body via a first transmission path (301); a lens CPU (203) for performing the preset control process based on the control data according to the situation that the control data is received by the lens side first communication circuit and performing the generation process in a preset interval to generate the preset lens data representing the operating state of the interchangeable lens and making the generation process prior to the control process; a lens side second communication circuit (213) for transmitting the lens data to the camera body via a second transmission path different from the first transmission path according to the situation that
