I got an Amedeo adapter for my S Sonnar as Jonmanjiro had suggested and see no focus shift at f/1.5 on the M7.
BTW now I have the adapter which Nikkor 50mm should I get? 🙂
Ah-ha, so you did go with an Amedeo adapter Ray. Pretty cool combo hey. I have no problem focusing at f1.5 either on my ZI.
Now that you have the adapter, the next lens is an easy choice. Its gotta be a Millennium Nikkor 50/1.4!
