Hello,
I have this lens (first version as described in the http://zeissikonveb.de/start/objektive/normalobjektive/prakticar%201%2C4.html), the focus ring is not as fluid as it should be, especially at the bottom distances (1m). Could you describe how it can be relubricated?
Thanks in advance
Br
Giorgio
