This is why I love my 50 f1.4, It's not a 1.2 but the best I can manage, it may not be the sharpest knife in the box but that isn't my main criteria.

In my opinion the high ISO available in modern bodies does not make fast lenses obsolete from an artistic point of view, what Hi ISO does is help to solve fast subject/low light difficulties.

I agree about the new cameras not making the fast lenses obsolete but they reduce the need unless you want the limited DOF.   At that point Hi ISO can become a nuisance as in sunny conditions 1/8000 is still not fast enough to expose correctly at ISO 200 and f1.2.
