The plain fact of the matter is that the current 50/1.2L was a very carefully designed lens. Compromises were obviously made (in stark contrast to the 50/1.0 in which no compromises were made) and the results reflect that. Even with these compromises the 50/1.2L is the best fast aperture 50mm lens that money can buy today. The only reason people make such a big deal about it is that expectations are so low for the other 50s (they're cheap, so it's ok if they suck).
What I find weird is that if it was so carefully designed, then why is it softer than the Canon FDn 50/1.2L? Why does it have focus shift, which the FDn does not. And so on. I get the EF 1.0 is a compromise, because it's more of an experiment/PR-thing. However, what boggles my mind is EF 1.2L being worse than the FDn in pretty much all ways (except the AF part :P).
Time between the introductions is 27 years, going backwards instead of improving or at least being able to keep on the same level makes me sad. I like the focal length, but currently there just is no good AF 50mm lens for Canon.
