Hi does anyone know how to mount this len on M series camera, it seem like the mounting is design for leicaflex mounting. I actually had a adaptor for Leicaflex mounting to M-mounting but after fixing up into M-series camera unable to focus. Another question is unable to focus on M-series camera with visoflex attaching with leicaflex adaptor on leicaflex mounting lense. What suggestion for leicaflex mounting lense attach on M-series body.
