    摘要： A first lens unit performing communication with an image pickup apparatus (10) with a first voltage (V1) and a second lens unit performing communication with the image pickup apparatus with a second voltage (V2) are selectively attached to the image pickup apparatus. The image pickup apparatus includes a controller (18) configured to operate with a third voltage (V3) 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 (90, 20) 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.

    摘要翻译： 本发明提供以下相机。 第一相机侧接触针是对应于由相机附件的耦合引起的信号变化的检测的引脚。 第二相机侧接触针是相应于与耦合的摄像机附件进行通信的电源供给相对应的引脚。 第三相机侧接触针是对应于向相机附件的致动器提供驱动力的销。 第一，第二和第三相机侧接触销以这样的方式设置，即当相机侧安装座从第一状态转移到第二状态时，第三相机侧接触销接触第一和第二附件侧 接触表面，第二相机侧接触针接触第一附件侧接触表面，并且第一相机侧接触针不接触第二和第三附件侧接触表面。
