I had the 50 1.4 ASPH and sold it, now I have a 50 1.0 Noctilux and I will keep it until the day I die
Now lets see : the 1.4 ASPH is the most versatile overwall, no question about it.
Perfect bokeh, controlled lens, superb in all aspects. Afterall, the best 50mm in the whole World. That gotta say something.
I got to play with a 0.95 Nocti and its a heck of a lens : its the 1.0 Nocti without all its flaws and corrected : much sharper on the corners, corrected the backfocous, etc etc.
The 1.0 for me its the keeper. It draws in a special way. The 0.95 still has Noctilux DNA but much more "controlled" , if you know what I mean.
1.0 Nocti its a special lens. Its big, bulky, heavy but... its magical. And as will all magical things its full of imperfections. But when you get it right.. oh boy...
here's a couple of mine with a Noctilux :
