I've had a dozen of different old ~50mm lenses, including several Minoltas. They are cheap and widely available, so it doesn't take much to build a big collection. Some samples are here . I got rid of most of them, still have Minolta 50/1.7 and 45/2 -- they are too cheap to bother selling them, and keeping Canon FD 50/1.4 for sentimental value, and it's probably the best of any other old 50mm lens. Still, the Sony 50/1.8 was noticeably better than any of those. Here is a comparison with Rokkor 50/1.4

I also tried some of them on A7 and thought they were better on FF, still too soft wide open, bad corners, too severe halation and CA -- they were actually worse on FF than SEL 50/1.8 on a NEX.

because I don't have the Sony I can't and won't argue if the Sony is better than legacy 50mm lenses, but one thing I can say for certain: your sample shown taken with the Rokkor is not representative of a legacy 50mm at all!

It either had been taken with a faulty lens or simply had been very badly taken. None of my 40+ legacy normal lenses would look that bad @f2. Unfortunately I don't have the Rokkor-X 1.4/50, which I also have, with my right now, but e.g. a 50% crop of a fast and dirty take I just did with a S-M-C Takumar 1.4/50 @f2 on NEX5N:

Sorry to disappoint you, but all your guesses are wrong. Show some valid tests if you want to prove any of your statements. And for now, here are some more tests with the old manual lenses. They are not surprisingly tested very much alike with few exceptions, and quite behind the Sony's lenses, which actually aren't the best of the breed either.

note : the best lens in your test in terms of sharpness @ its respective sweetspot is not the sel but the fd 28/2.0 ...
