I bougt an Elmar 9cm/4 non collapsible version but unfortunately the lens has got focus problem.
Today i disassembled the lens but couldn't solve the problem.
Anybody knows how i can adjust and align the focus?
Tks in advance
 
What problem is it having: If the actual focus does not agree with the Rangefinder, does it focus in front or in back of the point you want?

I had an 9cm F4 Elmar that front-focused. I had to take the optics module out and grind down the end of the focus mount so the optics module would screw in deeper.

The problem is that the distance that indicates the lens and the real world is different ...i mean another lens shows X meters but Elmar Y meters.
