This lens was sold with Zenit SLR cameras. The prices for the M-4 version are a bit lower, they have a lower resolution as the top classed models M-6 and M-7. The later Helios 44 M series lenses were classed from M with the lowest resolution (38/19 lpmm) to M-7 (50/30 lpmm, a bit hard to find). The M-4 has 41/20 lpmm, it's a very decent lens. I could see no difference in sharpness to the M-6, but judge yourelf. This one is an 6-blade KMZ version from the 1990, with automatic aperture. Wide open it's quite soft towards edges. Stopped down a little bit, it gets immediately sharp. The lens has good close focussing capablities. It is a small Helios 44 variant, but it's still relatively big and 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.
