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.
