Well that is a lot of info on MTFs, but as far as I am aware most manufacturers do not test the real MTFs for lenses, they are mostly theoretical, and when they do, they cherry pick. I don’t doubt that the APO is an extraordinary lens, but remember, Leica are salespeople, trying to sell high quality lenses and a myth to those with deep pockets.
Looking very closely at Fred’s testing on a large screen, it is hard to see how the GM could be bettered - and I trust my eyes. Even if the APO does turn out to be better ‘off axis’ which from looking at the GM results I very much, doubt, it will very definitely not result in the GM ‘not coming close’, and that is exactly hyperbole.
The Leica SL APO 35 really is one of the best of the best. As we learned, the modern Leica APO is a big factor in why the SL 35 APO reaches the nosebleed MTF measurements that it does even with potential of diffraction at F8. Mr. Karbe also mentioned he had plenty of room in the SL APO prime standardized lens barrel to work some magic too on the 35 APO lens forumula too.
With that said, and since I shoot both SL APO primes and Sony GM primes, when comparing the GM 35 with one of perhaps the best FF 35mm primes, I am impressed with what Sony has done and continues to do with their GM 35 and other GM lenses.
In one of your previous comments on this thread you wrote "The [SL] Apo Summicrons are monsters" Just for fun, here is another perspective and yes, the Sony GM is a 1.4 lens and the other is an F2 lens. So you might say the SL APO 35/2 is a large F2 lens, but again we all know why:
