Today I had more time to actally look at the 100% center crop samples (I hope that with a little pixel peeping I wouldn't annoy you) and what struck me was the difference in sharpnes and CA/PF between the two lenses at apertures f/2.8, f/4 and f/5.6. The Topcor seems to resolve better and there is almost no CA at f/2.8, while the Nokton has some even at f/4. At f/8 I am not able to distinguish between the two.

The only advantage in sharpness of the Nokton is at apertures f/1.4 and f/2. But then from f/2.8 the game changes and the Topcor resolves much better than the Nokton.
These are 200% crops:


nokton@f/2.8


topcor@f/2.8


nokton@f/4


topcor@f4


nokton@f/5.6


topcor@f/5.6
