Soviet cameras were usually junk, but their lenses were phenomenal value and exceedingly well built. Why? Because the lenses were a product that could be used by the military, and thus built to work. The cameras were built for civilians, and thus garbage. I've had several Kiev branded lenses, and they were nothing to sneeze at. Same with Combloc weapons, which are all simple, stout, and dependable designs. As for Zeiss Jena, when the Soviets got East Germany, they took most of the Zeiss manufacturing equipment other than what the Americans could spirit away. But, they were essentially all the proper Carl Zeiss designs made on the same Carl Zeiss equipment, just with inferior optical coatings.
