My first post on this interesting website: hope it is worthy...
I think we have a thirst nowadays for old-style lenses with so-called imperfections. Just as the old 1960s-1990s Summilux 1.4/35mm for Leicas is hard to find now and much liked despite the better behaved ASPH versions made since. In the case of the Leica the compact size helps too, no doubt.
I too am hoping to go out and buy the 1.4/35mm Nikkor once more after seeing those characterful wide open shots. I am so sad I sold my Noct though; I cannot afford to get another.
Maybe, as with a face, a lens with an imperfection draws more attention to its beauty because of a distinct feature. Which happens to be indistinct, in the case of the defocused background!
What you say is one aspect of the effect you will see showing this kind of pictures on the interweb. Some people really hate this "icorrect" rendering as they say. Some love it.
If you can live with this comtoversy, good. I can.
Yet I also own or can borrow all these "perfect" expensive lenses from friends any time.
