Summarit wont focus at infinity

[jc48375]

I inherited a nice conditioned Summarit and it works really well with my Sony A7II..

However, it won't focus into infinity on my Sony a7II or Leica M2 or Zeiss Ikon ZM. My 50mm Zeiss Sonnar will focus at infinity when mounted all these three cameras.

Is there any adjustment I can make on the Summarit at home so I don't have to send it away?

Cheers!

It has an infinity lock, right? Does it go all the way into the lock position until it clicks?

Yes, it goes into the infinity lock and stays lock - but the lens needs to rotate little bit more to focus on the infinity..

Or can I adjust the location of the infinity lock?

Maybe it was taken apart and reassembled wrong. But it seems strange that it would still work on the Sony. Is it bayonet or LTM?

I can't tell if this lens has been disassembled before... It's an M-mount..

It probably works on one Sony because digital adapters are often set so you can focus past infinity, just to be sure you can get there, to allow making a cheaper adapter. It doesn't matter, because it doesn't use the RF linkage to focus. Rather than messing around yourself, you should just send it to someone who knows what he's doing, so you don't turn your free lens into a free, worthless lens.
