I went to take a look yesterday and have changed my mind about this camera. It doesn't look as good in real life as it does in the pictures and videos. The dials look nice but feel cheap to the touch when adjustments are made.
The exposure priority dial at the extreme right M A S P is awful. It needs to be pulled up before it turns and it feels like it's on the verge of falling off.
"You buy the Df with your heart not your head" is what many reviewers have remarked. If it felt more solid and classy, I would have bought it. It felt cheap so I'm not. Besides I already have the D4 which uses exactly the same sensor and can get far more out of it.
