New focuusing issue....

My 180mm has started to not move the focus ring much, it is not the usual AF motor failure.  If I do a rough focus then the AF will fine tune, but it will not do that from a wrong focus point.....

 

Any ideas, it is cold here currently but it is not affecting any other lens.

I shot my S in Japan recently in minus 3 degrees. The only significant problem I saw was battery life sucks with the S in the cold. As for your lens issue maybe it’s just the start of a AF failure but from what I remember with my 3 failures was it was instant and a squealing noise to go with it.

No reason not to send it in. The AF mechanism may be twin: one for micro-adjustments, one for longer focus changes. Anyway sounds like something you cannot live with. Get it upgraded, and achieve peace of mind.

Did it change behavior after removing the lens and remounting?

I have retried a few times with no difference, my AF failures have all been instant.  I will contact Leica UK, but not send the lens off until the new year...
