I have a similar issue with an older M42 lens. Try to calculate the actual focusing distance when the lens reads infinity. Let's say it is 10 meters. You would need to focus the lens to infinity, loose the focusing ring and move it until it reads 10 meters. Then it will be aligned and your lens reading vs. actual should be the same. That will also give it more travel to reach proper infinity. Hope this helps. Thanks! Ismael
