Marty, you are saying that, in your experience"......At distances under 
1.5-2 m the Summilux asph needs to be stopped down to f4 or
so to equal the 50/2 Summicron and related lenses in a number of ways.  

To equal the Summicron at what aperture, also f4 or f2? Only at the same 
aperture would be directly comparable. Of course the 50
asph is definitely better at f1.4 than the Summicron at f1.4 ;-)
