Name "Nokton" is well-deserved. Here are a few shots @f/1.0, 1.4, 2.0. Zf, handheld, 1/60s, -1EV.
This lens is sharp at daytime, but here it looks crazy sharp: I took similar test pics some time ago with the Noct 58/1.2 and the Canon FD 50/1.4 and the results were quite inferior.
Only the coma and halos look more developed than with the Nikkor but bright night sources are seldom of interest anyway.
