Leica 50mm f2 Summicron-M (Type V) (Black, 11826 / 11719)

There was fungus on the front element that managed to eat away at the coatings quite badly. This will slightly affect image quality. Luckily, the fungus did not spread inside the lens and cleaned off nicely, so it won't get worse and only the coating damage remains. There's also a small scratch on the front element, though that won't affect images at all. Otherwise working well!
