Abstract
An imaging apparatus capable of mounting an interchangeable lens thereon includes first and second terminals for communicating with the interchangeable lens, and a control unit capable of switching between a first communication mode in which a clock signal is output from the first terminal and communication is performed using the second terminal based on the clock signal and a second communication mode in which communication is performed using the second terminal without outputting the clock signal from the first terminal. The control unit is configured to output a predetermined signal from the first terminal to the interchangeable lens when a predetermined condition is not satisfied in the second communication mode.
