Leica Summicron-M 50mm f2 (type 5) what kind of battery_Silver Oxide in excellent conditionThe Leica Summicron M 50mm f2 is a classic standard lens for Leica M mount cameras. In excellent condition, with smooth focusing and light internal dust. Diaphragm moves well, but it's worth noting that there is a touch of oil on the blades which does not affect function. This version of the Summicron also has a built in retractable hood, which is a feature that should be on every lens. Only very minimal cosmetic wear a nice lens.
