Leica 21mm f4 Super-Angulon-R (3-Cam) (11813)

The mechanisms have been cleaned, lubricated, and adjusted as necessary. The inner elements have been cleaned. There are moderate scratches on the lens elements that will slightly affect image quality. There's a bit of play in the focus, but it won't significantly affect use. It shows minor external wear, including a missing red dot on the lens barrel, but otherwise works well!
