I'm sure that I see him, but that the camera sees it?
For the shake reduction to work, the focal length of the lens is required to be known. If you put a lens on the camera that does not report its focal length through the electrical contacts, the camera asks you to input the focal length.

If you are not being asked to input focal length at power on, then your lens is talking to the camera.

I hope that helps.
