Took a test shot scenario for anyone interested in the Sony A1 with 50mm f1.2 GM vs the M11 with Noctilux f0.95.

Focus point is the logo on both cameras - red dot on the Leica and A1 on the Sony.
As you can see, no issues with sharpness either side wide open. I'd say that the Sony 50 is a bit more well behaved when it comes to handling colour fringing, especially purple fringing which the Noctilux is much worse at.
The minimum focus distance is better on the Sony 50 than the Leica which is my only real negative for the Leica outside of its weight. The M11 + Noctilux is a very heavy combo which has very limited ergonomics vs the Sony A1 which is designed around modern ergonomics.
Bokeh wise, noctilux is just a monster. It's the reason for buying such a lens and the way it makes more distant objects "pop" is legendary.
Now I'm just waiting for the weather to actually improve so I can go and take some proper photos!
