As stated under each pictures, a Df, the ubiquitous small camera that can see in the dark and reminds me of my FM2n's (I have three of those, each with a different shutter) :-) ! Since my D3x is only used for some paid work and when 24MP is really needed (not often)!
From time to time each of us meet the "almost" perfect camera for his own use and practice, it happens several times in life and now is my Df moment... :-)
Gee... Thanks a lot Bjørn... :-)
