Hi guys!
I have a problem with that version...
Focusing barrel just stuck somewhere under "focusing barrel outside"(5) it that guide. It moves like few degrees, and just stops on something like some metal detail.
It stuck when I just use lens in everyday shooting. I move the ring, and it starts sounds like its some kind of sand inside, and some few moves later it just stop. And I can't remove that "outside barrel" because of it... Crying or Very sad

you probably didn't put middle part of the lens with glass and aperture correctly back into the rest of the lens, so it grinds. it has to be put back parallel precisely

I just bought this lens about month ago. It is first time i open it.
Insides looks like fresh lubricated..
Maybe previous owner have not attach it correctly while do this. (but it worked nice like few weeks)
I have no idea, how to take off this stuck part...

Ok, something is solved, something is not....
I remove lens block, and found this:


There is screw-ring(A) that holding focus ring. It was screws on really tight, and focus ring just cant move... But, if I slightly release it, focus ring moves with that ring, and just screwing it off, and lens block not moving, when placed back.
How is this part works? Confused

**Found it! The big ring with screw(B), was very tight too. Release it a little, then, holding that ring, screw on focus rings holder(focus ring must be always on infinity mark).

You must 1. rotate B ring the way it can focus from 0,35 to infinite; 2. you rotate the A ring to keep the B-ring in that position Wink
