Is it possible to read distance from manual lenses (Zeiss EF)?

    There is no communication from the manual lens to the camera body, so it is not possible to read any data from the older Zeiss lenses.

    The Zeiss EF models apparently have focus confirmation, but that is done without any lens data information. As far as I can tell only genuine Canon lenses have focus distance info -- none of the Sigma or Tamron lenses tested have reported any distance.
