This old lens
was sold for Zenit SLR cameras. It
can
be found for moderate prices because of the compatibility problem, it's
nevertheless a decent moderate wide angle lens. Wide open it's
sharp already, a bit soft towards the edges, but at least as good as
others. Stopped down is fine. The lens has only some
close focussing capablities. Seen the aperture (F 2.8), size and weight
are fine.
The M39 Zenit Mount is the same thread as ordinary M39 (Leica), but
a different flange focal distance. Please refer to the russian
lens page.
