Update... I'm having issues focusing at infinity using the rangefinder.  All other focal lengths are fine.... To be continued.  

The RF coupling can't be calibrated and will likely be off at either end of the scale. I have two copies and one is fine near infinity, the other is fine near 70cm, but neither cover the full range. Since the coupling is machined into the rear element mount, this can't be changed.

Good news: If there's an issue specifically with infinity, e.g. you can't reach it, you can adjust the lens. Remove the rear mount plate by undoing the four screws. That gets you to the hard-stop adjustments (PH00) for both closest and infinity focus. They have about 1mm travel either side for adjustment, that should be enough.

Of course, all of this assumes a reasonable camera RF calibration. If you never used >=90mm lenses before, there's a chance it might be off by a tiny amount as well.

As to the question about negative scanning, that's indeed my intended purpose. I'm waiting for an easy35 to arrive, which I plan to use with my color M11 to scan. If that works, it'll be a much more portable system than my S5 or X2D based scanning setups.

I have same setup. I used to scan using leica copy stand paired with m11 or m10-r, 50mm Apo summicron and LED board. But now with easy35 paired Laowa 85mm f5.6, scanning is much better.
