He says that the non ASPH Summicron-M 35mm at F2.0 is almost identical to
Summilux-M ASPH 35mm at F 1.4.
I guess with my Summicron-M 35mm ASPH I don't have to worry about such wide open "character".
I can crank it open and still get excellence that won't be more difficult to print.
This keeps my need to "upgrade" and get the 1.4 ASPH down. 
I like my lenses to not get funny on me wide open. My words: "get funny"
