I had to build up the RF cam on my V1 35 F1.2 Nokton for use on my M9, I added one layer of copper tape to the RF cam. Out of the factory, it was optimized for Film in the Bessa R2. I didn't complain, 5 minute fix. Same with the 50/1.1 Nokton- 1 layer of tape on the RF Cam, easy fix.
I have two 7Artisans 50mm F1.1, they are Sonnar formula lenses. Lens 1- perfect focus on my M9 out of the box. Second lens: I optimized for my M Monochrom using an Orange filter. The adjustable RF cam is wonderful, saved me the trouble of cutting copper tape.
Shoot the lens on your camera wide-open and close up, using a ruler for a target. Mark the point of focus. If it needs adjusting- use the included tool and move the cam slightly. Chances are that a wide angle F2 lens is going to be fine with film out of the box. Put it on a 24+ MPixel camera, pixel peep, you might need to adjust it. 5 minute job at that point.
