Leica 5cm F2 Summicron Collapsible Early 920355
This Leica 5cm f2 Summicron Lens (Silver, Collapsible), #920355, 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, but there's some oil on the blades. 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 a vintage plastic Leica lens case and front & rear caps. Please refer to the photos for details.
