Hello folks, New member here. Though I've posted a few pictures on the "Show what your NEX looks like with adapted lenses" thread, this is my first initiated thread. The subject line says it all. I've been asked by a friend whether I am aware of a Mamiya CS mount adapter to NEX. He has tried a workaround by means of using a 3d printed plastic CS to EOS adapter and an EOS to NEX adapter. The trouble is, the CS to EOS adapter is friction only, and doesn't lock in place, and it's very loose, making it impossible to easily focus or adjust the aperture on the lens. I'm not aware of any direct adapter. Does anyone out there know of one? Or is his only option to glue the CS and EOS adapters together? Thanks in advance, Ed B.
