I just got a 1:2/50 Summicron in beautiful condition. But I cannot rotate the focus ring (in neither direction), even if i pull it to the front.

The ring stucks at 1m position, see picture.

Any tips to fix this? 

Thanks in advance...

Maybe the condition is not so beautiful? Either it has not been used in decades polymerizing the lubricant or it has had a knock damaging if the focus mechanism. Return it or send it to one of the trusted repair shops.

Normal in this position, close range

it waits for the optical close device to push the ball ...

with your thumb, push on the ball, then it would turn.

 

Or push the focus ring forward, then turn to normal range, it would turn freely.

edit,

do what Jaap told you.

Sorry, I saw it at close range.

That would make sense if I want to tocus closer than 1m; but I cannot turn focus to infinity, too...
By the way, when pushing the ball It does not move in fully, so I cannot put on the goggles.

With the focus at 1 mtr push the goggles on, then it will let you pull the front out and turn it past the stop into the close range.do the reverse to move back to the distance range.

There are other threads about this and I have read that there are two version of the dual range goggles with slightly different shapes to the connection, I don’t know if the wrong goggles will fit the other version of goggles and lens. But your goggles should hopefully fit past the ball.

Thanks four your comment, but as I wrote: even if I pull the focus ring to the front, I cannot rotate, in neither direction.

Thanks for your comments. I went to a Leica store, and they solved the problem.
The lens has not been used for decades and as a result the focus ring has seized. Now everything works.

Happy to hear that it turns 😃.

Are the lens elements fine ?

Use it love it,

take nice picture (I have three DR, I don't know why ! )
