<p>When a lens unit with a digital serial interface was connected to a camera unit without the interface, there arose the problem that setting was disabled of a mode of the lens unit from the side of the camera unit. The present invention provides a lens unit, solving the above problem, the lens unit being connected to the camera unit and being selectively set either in a lens mode in which control is effected according to a control signal from the lens unit, or in a second camera mode, in which control is effected according to a control signal from the camera unit, wherein when a signal for setting of mode is absent for input from the camera unit into the lens unit with a lapse of a predetermined time or more after on of power supply, a setting circuit sets the mode in which control is effected according to the control signal from the lens unit. <IMAGE></p> |
