Blur circles are a function of the physical size of the aperture, its shape, *and* image magnification. Smooth blur circles that overlap make smooth out-of-focus rendition.
I have a pre-order of the 58/0.95 Noct via my personal Nikon contact at Nikon Nordic. The Nikon subsidiaries do not take normal pre-orders for this lens yet, as it still is on a prototype stage of development.
