Even when the camera is turned off there is still some minimal power flowing to monitoring things. I do not know if that includes the lens mount. But if you insert a battery with the camera turned off, the "memory card activity" light will light up for a few seconds as the camera checks the status of any inserted memory card. | |

But the lens didn't always click in place correctly on the connection tube as the connection tube(s) connectors had a little bit of play, so this might have yielded a result similar to detaching the lens from the tube(s) without disconnecting the tube(s) from the camera first. | |
