Provided is a lens apparatus in which serial communication and parallel communication between a camera body and the lens apparatus are performed and resumption of the serial communication is accomplished after occurrence of a communication error, and controlling of a controlled object being controlled through the parallel communication is transferred to temporally controlling through the serial communication, in which, by setting a state of the controlled object when the controlling is transferred to controlling through the serial communication, to be coincident with a state during controlling through the parallel communication, the controlled object to be controlled through the parallel communication is not affected by an effect caused due to a communication error in the serial communication.
