Cosina Voigtlander 125mm 2.5 Apo Lanthar repair

[Bjørn Solberg]

Bought this http://nikongear.net/revival/index.php/topic,2711.msg39833.html#msg39833  a bargain.

But now I have a (small?)repair issue, the lens is a little loose where indicated on the photo.

(Photo used is borrowed from the seller)

Big issue to repair?

[Erik Lund]

Is the whole lens wobbling back and forth or is the focus ring loose, what do mean by loose?


Not a big deal to take it apart,,, just take care.



BTW i'm obviously the previous owner,,,

Thanks for reply,

Focus ring is tight only the end part  is wiggling a bit. Maybe it does not affect picture quality much?

[Seapy]

If it's just the bayonet mount then they do come loose, just needs tightening up?

[Erik Lund]

Then it is most likely the next interface that is loose, below the mount.
It is of outmost importance that these three screws are tightened down, the risk of breaking this inner mount is rather high, it's the achilles heel of the design quite literally.
Three thin L shaped prongs go deep down into the lens and is held down by three tiny screws, tiny for such a heavy lens.
These are the three most famous screws,,,     

You see them clearly in image two in this old thread from or our ancestry site,,,
