摘要： A first lens unit performing communication with an image pickup apparatus with a first voltage and a second lens unit performing communication with the image pickup apparatus with a second voltage are selectively attached to the image pickup apparatus. The image pickup apparatus includes a controller configured to operate with a third voltage different from at least one of the first and second voltages to output a signal for the communication with the first and second lens units, and a determiner configured to determine the type of the lens unit attached to the image pickup apparatus. The controller is configured to produce, as a voltage of the signal for the communication, from the third voltage, one of the first and second voltages corresponding to a determination result of the determiner.

摘要： 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.

摘要： The camera side mount is brought, by relative rotation with the accessory side mount, from a first state where each accessory side bayonet claw is inserted between the camera side bayonet claws into a second state where the camera side and accessory side bayonet claws engage with each other. The leaf spring biasing the camera side contact pins in the protruding direction is disposed between the camera side mount and the camera body. When the camera being in the normal position is viewed from the direction facing the camera side mount, the leaf spring extends from both sides of the mount center line, which extends from the center of the camera side mount in the direction of gravity, toward the camera side contact pins. The camera side contact pins are arranged at positions other than a position on the mount center line.
