This old lens was sold with early Zenit SLR cameras. The old Zenit
version
can
be found for moderate prices because of the compatibility problem, it's
nevertheless a very decent lens. This is an
8-blade version from KMZ, made in the 1960s. Wide open it's a bit soft and has a
hint of shades at edges, but it's usable. Stopped down a little
bit, it's
sharp already. The lens has good
close focussing capablities. It is relatively big and heavy. It doesn't
close the aperture automatically, it stays open for focus when you set
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.
For the "Bokeh" of the different Helios 44 lenses I have made a separate page.
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.
