D4 is a fucking tank and the Df has the same sensor, originally I was going to get a D4 until the Df came out and I could have the same sensor in something that looks cool and weighs as much as a Rebel.
D800 I can have roughly the same footprint with a grip and break it down to a single battery to fit in an Ikelite housing, also the D4 weighs more so if I put it in a housing, if they even make one, it will immediately sink to the bottom where the D800 is a little more buoyant.
Resolution was another one, 36mp underwater is cool, gives me tons of real estate for fixing shit in post. 16mp is plenty for everything else honestly and the D4 sensor is just absurd with what it can do in low light even by today's standard.
On the Df the control wheels only work the aperture on the front, and the back one doesn't work a lot of things I actually had to pick it up to look.
Canon, I love their cameras and I still have a couple, I have an original 5D Classic and most of my L glass setup, I loved it too much to part with it completely and it has some things it does that the Nikon doesn't, like adapt Nikon manual focus lenses to a split-image focus screen and shoot an image that looks like film. I still have my old Rebel XTi and I think I'm going to IR convert it.
The big thing about Nikon for me was legacy glass, I already had a pretty extensive Nikon 35mm system. A digital body was the next logical upgrade and then the Df came out and I had to have one. I'd like to think if Canon made something like an AE-1D I would have stayed Canon but I loved the dials and stuff on the Df in a full frame sensor and a D4 sensor at that. All the other similar offerings were APS-C or m4/3 and I wanted that FF real estate.
I will give you that, all of the Nikon eyecups pretty much suck ass except for the round ones for the D800, F5, etc. I do like those it's simple and does the job.
Canons are good for ergonomics too, I loved mine and still do.
