I dont have to be a user to find the design awkward. The camera is much bulkier than a manual film Nikon and it is missing a manual focusing aid (split screen or similar).
If you like the camera, thats good for you, but dont expect everyone else to ignore the obvious (see above).
It is OK for me to ignore the obvious, but not you!!!
The Df is smaller and less bulky than my FM2n with a MD12, and is no where near the weight and heft of a F3 with a MD4, smaller than a F4 or F5 by a country mile.
Of course, it is thicker than a plain-jane FM2 or FE2, but in the hand there is not practical difference. Feels and operates just like any of the 3rd generation Nikons, FM2, FE2, F3. I own and have used all of these cameras in the past 30 years. My workhorse camera has been the plain prism Nikon F. For all practical intents and purposes, I cannot tell the difference in use between my Nikon F and the Df, with exception of the flashing lights in the viewfinder and the obvious difference of not needing film.
As for missing a manual focusing aid, it is not... I have never used a split image or etc in any of my film Nikons. I have always used the 'E-type' screen, I even went so far as to have my old Nikkormat FTn modified by having a camera technician install an 'E-type' screen from a FM2, to get rid of the split image. The Df focuses manual lenses as well as my Nikon F, maybe not better, but as well, which is important since I do not own an AF lens.
If you enjoyed using an F3, FM2, FE2, you will find the Df very easy to use. Different, but equally easy and comfortable to use.
My criteria for the Nikon Df was that it had to be able to focus as well as my Nikon F and allow me to shoot just as if I were using the F. It did. If the Df had not passed this test by 100%, I would have not bought it, just like I have not bought a D3, D700, D4, D600, or D800, all very good cameras, but not for me and my way of being a photographer.
The Df is obviously not the camera for you, but I am very glad that Nikon finally made a DSLR for me.
