But who needs an adapter when the Leica S lenses are so superb, better than the Hasselblad or Contax lenses IMO, just bigger and heavier. And with the CCD sensor, a knock-out combination. Just watch out for the corrosion issues and hope the camera (and the early AF lens motors) does not need any quite likely expensive and possibly impossible repairs.I still have my Leica S2 which I bought used in 2017 for 2k. It needs an (sort of expensive) adapter for HC and Contax lenses, but works actually pretty well despite its age. I keep it because it is not worth selling it and from time to time it is fun to use the S2. Not sure though I understand you want a CCD based camera.
