This old lens was sold with early Zenit SLR cameras. The old Zenit
be found for very moderate prices because of the compatibility problem,
nevertheless a very decent lens. This is a second one of the old
8-blade version from KMZ, slightly newer than the first one (N0266115 vs.
N0256726), just to test the variations within the production series.

open it's a bit soft and has a
hint of shades at edges, but it's usable. Stopped down a little

a smaller stop and you have to turn a ring to close it to the value you
preset separately. A nice lens which offers
one usable stop more than a standard lens.
