when i had mamiya, i felt the 210 was superior to the 200/2.8 apo and it autofocuses too, although not fast at f4.0. the 150 af is very sharp too with nice bokeh. i too have the 110/2.0 and it is in a different league. son did have one for sale and it may still be available; he was selling it under contax 645 equipment on ebay, but with another adapter, it will work on mamiya.
the zeiss lenses with shutters cannot use the leaf shutters on the mamiya 645 afd series. i believe the older mamiya leaf shutter lenses will work, but you need a double cable release to trigger the leaf shutter and the focal plane shutter as i recall.
