Those look like excellent MTF performance. A little more astigmatism for the 35 than 50, but it is still very low and excellent across the frame performance from wide open.
Yes, perhaps the best we've seen in a 35/2 lens.
I mean, is it though? Look at the GM's MTF.
Granted, AFAIK Sony & Voigtlander both use calculated MTF instead of measured but at least from the MTF the Sony looks more impressive to me seeing that the Sony is at 1.4 and there's less astigmatism. At f2 I'd be very surprised if the APO does better.
