Thanks for the link Hugh. Perhaps not in the correct topic?
Good news "The lens is chipped for providing communication between the lens and camera body on compatible Z-mount cameras. In addition to enabling EXIF data, this also enables proper in-body image stabilization on compatible cameras, as well as support for the various focusing assist functions. This is all possible due to a licensing agreement Cosina has struck with Nikon that allowed it to develop and manufacture this unit."
