The 'new' Nikkor-N 5cm f/1.1 lens in RF(S) mount is, not unexpectedly, fabulous for IR set wide open. The IR 'blur and glow' is there in the plenty
There will be a hot spot starting to be bothersome at f/5.6, but hey why acquire such a lens and shot with it stopped all the way down??
Entire FX frame at f/1.1 with the PrimaLuxe Z5 and Hoya R-72. Weather was increasingly inclement and rain was imminent. However even under these dark conditions, the fast Nikkor helped keep shutter speeds up (around 1/800 for this picture).
