Nice!!! Makes me wonder if someone would be able to adapt my Contax G2 28mm Biogon to the old Contax RF mount.....may be I could even do this myself with the help of local fitter and turner????
Which Planar is that?(non-registered)
I am having the same idea of modifying a Contax G lens (most preferably 35mm Planar and 21mm Biogon) into Contax II or Nikon S mount, and then use them with a Contax II/Nikon S to Leica M-mount adapter.
