This Leica 5cm f2 Summicron Lens (Collapsible, First Batch), #921946, is in great condition with minor handling wear. I rate it cosmetically a (9). The lens extends and retracts properly and the aperture ring is smooth, but the focus ring is a bit stiff. The aperture functions properly, and the glass is clean and clear with no haze, marks, or fungus. There are a few faint specks of dust inside, but they do not affect image quality. This lens is for Leica screw mount/thread mount (LTM) and other E39 bodies. It includes front & rear caps.
