Is the 50/1.4 pre-asph Summilux sharp wide-open? I'm interested in type 2.

I have a DR cron but I sometimes need that extra stop of light. I know there are plenty of alternatives but I'm specifically interested in this lens. If it is half-decent wide-open then I'm not interested.

I always felt that f1.4 Leica lenses needed to be aspherical to be good....
