Closest focus

This was the standard lens for the later Zenit cameras, when they changed to M42 FFD. Already at F 3.5 it's o.k. in the center, but soft towards the edges. Stopped down it's good in my opinion, seen the price. It has some capabilities of close focussing. It's an extremely small and lightweight lens and very very cheap.
