stuck focus on 35/1.4 AI

(1/4) > >>

Bruno Schroder:
I have a 35/1.4 AI which is now almost completely stuck and almost impossible to focus. I'm tempted to clean it myself. I have not found anything relevant on internet, except a video opening it but not touching the helicoids. I also have, of course, read Richard's advices.

Has any of you already cleaned and regreased the helicoids on that lens? Any specific advice?

Many thanks.

richardHaw:
which 35/1.4 is it? this one? :o :o :o
if it is, send it to me. I will fix it for the blog...

Erik Lund:
Read Richards text on how to do it, and take care about marking etc. when removing the rear group, CRC elements,,,

richardHaw:
OMG, this has a CRC element!?  :o :o :o
