This is an official DJI cable to connect my Lumix G7 to my DJI Ronin SC. I set the camera to record without a lens, put the camera in USB/PC mode, plugged the cable into the gimbal and the other end into the camera, and the connection is instant. I didn't have to turn the camera off and on again or anything. Now my camera and gimbal are communicating. The connection is constant all the time, every time. The Lumix G7 is not on the compatibility list, but this cable allows my camera to connect to a gimbal.
