(EN) The present invention provides the following camera. A first camera-side contact pin is a pin corresponding to detection of a signal change caused by coupling of a camera accessory. A second camera-side contact pin is a pin corresponding to supply of power for communication with the coupled camera accessory. A third camera-side contact pin is a pin corresponding to supply of a driving force to an actuator of the camera accessory. The first, second, and third camera-side contact pins are disposed in such a manner that, when a camera-side mount shifts from a first state to a second state, the third camera-side contact pin contacts first and second accessory-side contact surfaces, the second camera-side contact pin contacts the first accessory-side contact surface, and the first camera-side contact pin does not contact the second and third accessory-side contact surfaces.
