Most look good.
With the first shot: I use the "Sparkle in the Eye" for the focusing with the RF. Makes a nice point source.
The 50/1.1 Nokton is territory that most will not go. I find using it with the RF is far easier than focusing the 55/1.2 on the Nikon Df.
I agree completely. I still find it difficult to nail the focus with the 'Lux f1.4 and the Nokton f1.1
A combination of less than perfect eyesight, too little light and slow shutter speeds can be a challenge. In all honesty, I need more practice and perhaps some schooling in the use of the camera.
