So, some weeks ago I picked this Carl Zeiss Jena Sonnar 2/50 at a flea market in Minsk, Belarus for $4. As you see, the lens comes in rather heavyweight TV camera mount. The protruding cog sector was used to control lens' aperture.
The lens is coated (confirming the T mark). The glass has a few bubbles, which dates this lens as late 1950s to early 1960s: in a short period where TV cameras were already getting common but glass manufacture method could still produce bubbles. Lens serial number is 4105577; anyone here who knows Jena S/N allocation years at that time?
The plan so far is to extract lens module from the mount and fit it into black Jupiter-8 barrel, making a rather unique black postwar Eastgerman coated screwmount Sonnar sample :)
