<p>@ Mag<br>
then I suggest:<br>
1. buy a no-name "what ever"-to-Leica S adapter<br>
2. buy from Mamiya service the M7 camera bajonet mount ring as a spare part<br>
3. unscrew the "what ever" bajonet side of the adapter, machine it shorter to match the M7 flange distance, add screw holes for the M7 camera bajonet mount ring and mount it<br>
4. Ask Mamiya service to disassemble back barrel of M7 lens to remove leaf shutter blades and eventually the aperture lever in case it interferes with the adapter and the Leica S baronet.<br>
Good luck, Christoph</p>

<p>Hi Jakob,<br /> it's not totally impossible to use Mamiya 7 lenses with your Leica S. The flange distance of M7 system is about 59mm which is rather large for a rangefinder camera. I don't know the Leica S flange distance but my guess is, it's shorter. So an adapter or an adaption of the lenses is theoretically possible. I did some modifications on M7 lenses (43, 65, 80, 150) in order to use them with my Alpa FPS and a IQ180 back because the lenses are very sharp (as you say;-) and they easily cover the 54x40 large sensor. The aperture is no problem because M7 does not have a spring aperture but the aperture is closed directly by the aperture ring at the lens. The central shutter is electromagnetic and normally closed. One has to disassemble the lens and remove the shutter blades to have the shutter open. Mamiya Germany did that service for me. They also disassembled some unused mechanical parts at the back barrel of the lens to avoid interferences with my customized adapter (which even allows shift movements on the FPS.)<br /> Enclosed a link for a 80MP pic by the M7 150f4.5 at open aperture.<br /> https://dl.dropboxusercontent.com/u/18437364/pictures/150mm-Mamiya-7-150f4.5-Apo%40f4.5.jpg</p>
