I stumbled across two of my old Contax lenses gathering dust on the camera shelf. I have the Zeiss 35-70 f/3.4 vario-sonnar, and the 200 f/4 tele-tessar. The 35-70 is well regarded. I don't remember the 200 being anything extraordinary.
Would like to pick up an adapter for the 35-70 for my 5D2, any recommendations on which will give the best functionality, with focus confirmation?
