Subject: [Leica] 35/1.4 Asph. vs. 2.0 Asph. vs. 2.0

All,

Let's assume for a moment that above 2.8 the optical performance of
these lenses are equivalent. 

The confusion (and conflicting reports) I've heard really concerns
whether is Summilux performs on par with the non-Asph. Summicron or with
the Asph. Summicron at large apertures. 

Can anyone point to performance data comparing the Summilux Asph. with
the Summicron Asph. AT 2.0 OR 2.8? Which is better?
