So - I have recently acquired this lens, and it's presenting a problem.
For some reason, it won't focus to infinity on my camera - an Olympus EM1.

I'm using a Kent Faith Leica-R to MFT adaptor.
The adaptor has a flange depth of 27.75mm.
The adaptor has been tested on someone else camera, with someone else's Leica R lenses, and it seems to work ok.

But me - I can only get objects in focus up to maybe 20 feet away, and that's it.

The lens seems to turn as I'd expect - it's maybe not quite as slick as my Takumar lenses - but turns well enough.
I'm not familiar with Leitz, or Leica lenses, so unsure what it should be like - but it seems to turn fine to me, and stops turning at bang on the infinity symbol.
Turning the lens the other way as far as it goes - it stops at almost a full revolution - maybe 340 degrees or so - not a full revolution but not far off.

So - any idea what could be causing this issue?
Lens seems to function well other than this.

It looks like this...

Sounds as if it not really a Leica-R version!?
