Be gentle when doing post processing of files from the fast lenses such as 50mm 1.2, 55mm 1.2 and Noct-Nikkor
If you use the 'sliders' too much or too aggressive in processing then the result will very quickly be harsh and rough looking,,,
My recommendation is to choose such lenses only if you would like an image with soft rendering, don't try to force sharpness into the image or you will end up with bad bokeh and a strange look of the file,,,
Instead of bumping up clearity, contrast and or sharpness, try with zero compensation or even pulling down these, maybe add colour or vibrance saturation only instead.
And as a final touch add selective sharpening only on the areas where the focal plane is!
