Sorry Mike .... just a side line comment.
As elsewhere, some of us up here in the North like that camera. In the triple selfie, there are two Df's, one is mine and the other belongs to Jakov. While he is a laid-back über-cool kind of guy, he definitively isn't Nordic !
I spoke about the actual Df sales with one of my Nikon Nordic contacts and he claimed the camera had sold 'reasonably well and above expectations', but wouldn't go into actual sales figure.
However, just like with the Nikon D2H in its day, there are very few Df cameras on the second-hand market. That might indicate the buyers do keep their cameras over time. Second-hand D3S cameras have also seen a shortage probably for the same reason.
