Hi Noel. Sorry to hear about this. I had a lens for my Rollei SL-35 once
that did this. It turned out there were a few set screws on the focusing
ring and the ring had slipped a bit. I just focused on an object that was a
measured 6 feet away, and then loosened the ring and turned it so it read 6
feet. I tightened them up, then focused on something at infinity to check.
I think I had to fine tune it a bit, but it worked just fine after that. I
knew that the camera body was adjusted fine, as all other lenses worked just
fine focusing to infinity.
I looked at my Leica lenses and I only see some set screws in my 90/2.8
lens. It is of the same vintage as the 100/4, so maybe it has set screws
that will allow you to ajust the focus ring. If not I guess the repair shop
is in its future.

Doug the lens is the 100 Macro Elmar. It used to focus to infinity, now it doesn't. The travel seems correct from stop to stop, but it just doesn't line up in the microprism.
Other lenses focus on the body OK, and the suspect lens does the same thing on another R body.
And, I don't have the doubler mounted, before someone asks! ; )
I suspect a trip to the repair shop is in order, unfortunately. As the lens works for near focus, and it is wildflower season, and I have a 90 and 135 R lens, that may have to wait until the leaves fall, as I want to use it for macro work on mountain flowers.
