I was doing a project tonight testing the low light performance of my Fuji X1 vs a Nikon Df. It was raining hard so I took my old long grey mac and black woolly balaclava. My favourite place for night shooting is under the streetlamp by the hospital and round the corner by the nurses home.
Some of the girls have pet names for me. I can't hear too well under the balaclava but they shout my nickname in greeting from their windows.
I can report that over 20mins the Nikon far outperformed the Fuji. The whole colour balance and especially the flesh tones were excellent under really tricky light and through blinds and curtains.
I'd post some samples but unfortunately the camera and card were seized for evidence when I was arrested.
