43mm 1.2 and 150mm 2.8 are curious choice

To me the big question with the 43 1.2 is exactly how sharp this lens will be when it is wide open. From my 'extreme limited' knowledge of fast lenses, they tend to be pretty soft wide open.

If that is the case with the 43 1.2 I suspect we will know we need to go to a bigger sensor to get narrower DOF.
