Indeed, it was equipped with a Schneider Kreuznach Xenon 50 mm f/2 lens. What makes a bit special the copy in my possession is a small white triangle (which means not coated) between marks that identify the lens and which is present only in a small number of copies, produced in Germany during 1948 for the domestic market. Of course this is only a little curiosity that adds nothing to the value of the camera itself, if not from the historical point of view.
