Just bought a mint s/h Df with a "silver ring" 50 1.8 in December (arrived in January)... As a D4 owner, I of course love the performance... I was saddened though not surprised at all to hear that the Df was discontinued. I had hoped until a few years ago that a DfII would be forthcoming, but was again saddened, though not surprised, that one never did.
In the few short months I have owned my Df, I have come to love it and have bought two lenses especially for it... one is shown below.
I hope that this camera has a lot of life left in it.
