This was the standard lens for the newer M39 cameras. The lenses are the same as in the collapsible version. There was a Zenit camera version, 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 no capabilities of close focussing. It's an extremely small and lightweight lens with good contrast and it's very very cheap.
