This lens was sold with Zenit SLR cameras. The prices for the M-6
version are a bit higher, they have a higher resolution. 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-6 has 45/25 lpmm, it's a very decent lens. This one is an 6-blade Valdai
the 1992, 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.
