You see that stabilizing arm extending from the body out to the lens head?

No, the Agfa's (later a Commie Iskra model), Zeiss-Ikon's and others had coupled rangefinders. > For exposure control I would guess that the lens is set exactly as per an > M, then the shutter speed is adjusted via the dial on top > (complete with A setting). An Auto setting implies that the metering is > TTL! Who needs an exposure meter on one of these? I doubt seriously that it can be TTL. That would be assuming it has a focal plane shutter and it obviously has a leaf shutter. They open and close when you take the shot, so they are not letting any light through until then. It would be over-kill to have TTL with such a mechanism. Daniel
