Not all of the pictures are taken at F1.  What really sets the Noctilux
apart from the other 50's is not how sharp it is but how it renders things.
 Erwin Puts has noted that it has very high flare (veiling flare)
suppression, which means there is detail recorded where the veil of flare
would obscure it.  An example of this quality is here:

You can see the bright window behind Boyd's head, which should cause flare.
 The picture though shows great shadow detail and a very smooth redition of
his skin and texture of his sweater (better visible in the actual print).
Look at the details and shadows of the chair behind him.  Remember the lens
has two sources of flare, the window above the chair and the window in the
right of the picture.

I stand to be corrected on my analysis of this, as I only know what I have
gleaned from Erwin Puts' posts.  Erwin may want to comment on this or you
may want to get the Photo Techniques magazine that has Erwin's article
about the Noctilux in it.
