M-42 / CANON EOS

 
   

   

To put a M-42 objective on analogical and numerical Canon EOS. It allows to keep the infinity focus. One loses the automatic preselection of dia (diaphragm functions manually) the photographic exposure meter functions with all the numerical cases (300D, 350D, 10D, 20D....) The ring new manufactured with hardened aluminium and is anodized in black. I have also rings to assemble on the EOS the objectives: Yashica/Contax, Nikon, Leitz.
