While I have used an Elmar and a Summitar and been happy with them, I have no idea about the various Russian and Ukrainian knock-offs of ancient designs and so have no basis for commenting on your comparison. I suspect that many others are in the same position. If you want good, modern, reasonably priced lenses for your LTM Leica, why not look at the Cosina offerings instead?
