I will share little secret with you. This procedure goes especially well with old alu Sonnars and Triotars, but don't use it on newer lenses.
You know the disinfection liquid used in hospitals by doctors and nurses for their hands? Well, put few drops from bottom side of the lens on inner housing , avoid glass of course. It will be easier if you focus on min. distance. This liquid is cool since it makes dried grease softer and also leaves some kind of lubricant behind that helps even more. If you won't use lens for a while you might have to repeat the procedure. Ebay sellers beware - if you'll write "smooth focussing" in the description you might get negative feedback since after lens reaches the buyer it will be stiff again  .

Would it be the same liquid as hydroalcoholic soap used to dry wash hands ?

Pancolart, I know you're not kidding me.
I just mentioned that I didn't fix it yet and despite that, I manage to take shots with it.

Hi, I have a Sonnar now (4/135) and the focus ring is absolutely stiff. I read some of you had a stiff focus, too. I cannot even wind a little bit.
I am not sure whether liquid helps.
What do you think?
It is a very nice lens, and I want to use it. It is fix at infinite ...
Best regards
Bernd from Dresden |

Hello Bernd.
Welcome here ! 
I've just have a look at my sonnar and triotar.
I'm surprised that my triotar is not so stiff today.
The smell makes me remind that I put a few drops of gun's oïl.
It works fine ! (avoid glass of course).
and I think you should try Pancolart's tip.

Oh, and you should try to dismount the front

| Oh yes, now I remember! Do you see the slotted tube in the back? Unscrew this and the whole optical block comes off at the front (only the focusing helicoid stays). Then you should be able to put the optical block back in the correct position. |
