Well, if the DF is small, then its alright.
Problem is, talking about size, it is not that small, almost the same size with the d610, hence a lot bigger than the d3200. People who looking for portability won't consider this camera imo, and since it is FF, the lenses will be big also.
The funny thing I found is, when Sony introduced the A7, so many people bashed it for having a compact body with big lenses and it's a pointless product.
Okay, now Nikon did almost the same thing. The DF is a SLR, the A7 is a mirrorless, so actually they can't be compared. But, since a lot of people thought that they are aimed to the same type of consumer (those who wanted great IQ in a small package), they will be compared together at the end.
Talking about the size, the DF is larger than the A7 by quite a lot, same to the weight. People might say it is good because it can used with Ai lenses and all present Nikon lenses. There's one thing that people didn't see on the A7, with Metabones adapter, it can use Canon and Nikon lenses also, and still retaining autofocus (just that it is slower than Zeiss on the camera).
Next point, the price. As you all can see, the DF is so damn overpriced, costing almost the same as the d800.

The technology inside is worse than the d800, some even worse than the d610. The only thing that's good is the D4 sensor, nothing else.
i can't understand why so many people praising the camera, there's really nothing good about it imo, other than the retro looks (well only the front and top, the rear is still a nikon DSLR). some people said it's a mini D4, well other than the same sensor, there isn't anything same.
I am a Canon user so i don't really care about the DF, but I jsut cant understand the fame it gets.
