This is the "normal" lens for the Pentacon Six made by Carl Zeiss Jena.
It is in excellent condition with light wear and works perfectly. The glass is clean and scratch-free with no haze, fungus, nor other issues. The focus is smooth and the aperture is dry and snappy.
A 3d printed rear lens cap is included. It is a tight fit. You have to push and "snap" it on to the lens mount.
