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.
