I'm not sure whether I understand the principle correctly - does this mean that this body could also autofocus manual focus lenses?  :blink: Intriguing thought.. but I remain skeptical for now. 

Yes, Zeiss contax lenses were manual, and in order to jump onto the AF bandwagon, Contax needed to move the film plane back and forward to focus. But the longer the focal length, the bigger the movements need to be, and the film plane could only move a little. So, it was more like you manual focussed close to focus, and the "AF" would move the final little part.

 

It worked so well that soon after Contax came with Zeiss AF lenses and real AF bodies .
