Digital version of the Nikon F3 or FM2 with the same sensor as the D600. No auto anything, including no auto focus. No stabilization.
The FM2, FE2 and F3 all have interchangeable backs. I've often wondered if a digital sensor back could be built as replacement back for these cameras. Much like Nikon and Kodak did with the Nikon F3. Only using a good modern day sensor.
