Object; To provide an exchangeable connecting device between a video camera and an automatic iris lens in which one common connector (k) is possible to connect different kind of lenses, and it is possible to use any kind of lens L1 or L2 without confirming the kind of lens to be used. Construction; an exchangeable connecting device between a video camera (M5) such as a CCD (Charged Couple Device) camera, area image sensor and automatic iris lens; in said video camera (M5) one of video control signals (1) amplified the output of light sensor is directly connected to an analog switch (t), while the other is connected through a galvanometer control circuit (p) to the analog switch (t), said analog switch (t) being connected to one common connector (k). When VS control type automatic iris lens (L1) is connected to the connector (k), a video control signal (1) amplified the output of light sensor is directly connected to the analog switch (t) and the common connector (k). When a DC control type automatic iris lens (L2), said analog switch (t) is switched and a video control signal (1) is amplified by said galvanometer control circuit p, so that the output of the light sensor is connected to one common connector (k) as a control current (2) of a galvanometer (f) corresponding to a video signal (IVpp).
