In a lens system in which a momentary mode in which AF is operated when an AF switch SW2 is pressed and a continuous mode in which the AF is continuously operated can be selected, a CPU uses the AF switch SW2 for use in the momentary mode as an AF stop switch, and stops an AF process when the AF switch SW2 is pressed (turned on) in the continuous mode.
