I purchased a Nikon Df in March 2014. I have shot about 22000 pictures so far with it and the image quality is impressive (my previous camera was a D300s and I also use a D800 at work). The Nikon D800 I use has about 10000 shots on it, no problems so far. I do find at low light the Df is clearly superior to the D800 particularly for moving subjects. I have shot about 50000 pictures with my D300 in some pretty rough conditions (yes I even dropped it) and never had a problem. Unfortunately, I have to admit the I have to admit though the design of the Df camera is fairly poor. The Df has gone back to Nikon twice in the 8 months I owned it and I really did not expect that from a camera of this level. In fact I have never, ever had to have a camera repaired in my life and I shoot in some pretty tough conditions. Both problems with the Df were with the exposure compensation dial (this to me says design flaw). After one month the setting locked on +3 and although I could move the dial, it had no effect on the changing the actual setting the camera used which made it basically useless. It was repaired under warranty, but it took a month. Now after only 6 more months of use it failed again, this time it is locked and will no longer turn, and it has gone back to Nikon yet again. Disappointing for sure. Has anyone else had similar problems with the Df? I requested they create a menu setting to change the exposure compensation that overrides the dial but they have ignored me.
