I bought a 50 Summicron in Dec 97. It was a little stiff, but also > had a rough part when focussing at near distaces. A year later (light > amateur use) it is very very smooth, perfect over all the range. My Summicron M was stiff when new. I systematically moved the focussing ring back and forth quite forcefully whenever I had nothing better to do (watching TV etc). It took care of the problem in a few weeks.
