I have the Helios MC 44M-4 variant with a KMZ logo.
MC as in multi-coated with 6 aperture blades. M42.
I use it on my Oly e-520 and it fits fine with the adapter.
It's a nice lens. Sharp in the center even wide open. It has nice smooth character. It also has relatively low contrast compared to my other standard lenses. Not that that's a bad thing though, since it's easy to bump up the contrast post process.
I've read low contrast is indicative of the Zeiss Biotar character as well. Makes sense since it's the same design.
I had to open up the lens to clean a touch of fungus behind the front element and also opened the back to keep the auto aperture pin in the pushed in position. It was easy to open it up, though when I opened the back there was a greasy little metal part stuck inside that had no conceivable purpose. When I say greasy I mean it was sitting in a blob of grease. Otherwise, the metal bit would have been rolling around making noise. It probably just landed there during the assembly. Kinda rough.
The focus ring is rather stiff, but generally usable, just a little slower than some.
I have other lenses I prefer such as the Pentacon 50/1.8 since it's a little smaller and focuses so close, though I think the Helios is a little sharper.
I made a few direct comparisons with the Pentacon, a Pentax M-f1.7 and my Minolta 58/1.4. It was mostly a wash at f2. The helios and the Pentax M are neck in neck in sharpness at smaller fstops, but again, the Minolta is no slouch either.
As far as character I love the Rokkor, but that's a very subjective conclusion.
