This old lens was sold with Zenit SLR cameras. The Zenit
be found for moderate prices because of the compatibility problem, it's
nevertheless a very decent lens. Wide open it's a bit soft, especially
at the edges, but it's perfectly usable. At F 8, it's
sharp. At F 16 it hardly gets blurred
due to diffraction, it's much better
than other lenses. Diffraction is a problem of the APS-C sensor size,
lens (see comparison page). 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.
The M39 Zenit Mount is the same thread as ordinary M39 (Leica), but
a different flange focal distance. Please refer to the russian
