This lens was sold with Zenit SLR cameras. It
can
be found for moderate prices, it's
nevertheless a very decent lens. This one is an 8-blade KMZ version from
the 1977, already with automatic aperture. Wide open it's very soft towards edges. Stopped down a little
bit, it gets immediately
sharp. The lens has good
close focussing capablities. It is relatively big and very heavy. 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.
