For the last 3 days I've been watching EVERY single video in Hi-Def I've found on youtube an vimeo from the 5d3 and D800. BTW, by doing a search with "last posted first" and hitting it every couple of hours I got to watch all the latest stuff, done with production units, rather than the older stuff done with prototypes and early firmware.
After my "research" on the D800 I'd say the problems are with its [b]720p mode[/b]. Already on the John Wright fashion video aliasing became very apparent on the shots at 720p done at 50fps (for slow motion). On some other videos, also at 720p, the moire and aliasing is certainly dreadful.
On the other hand, when shooting at 1080 all the nasyness go away and resolution shown is impressive. It's not free of some artifacts, but neither is the 5D3, which still shows moire at times (see video with the guy and a Lowepro bag)
I could only test a preproduction D800 for a few minutes at a NPS meeting, but being a Canon user I was totally lost there, didn't even know where to start. I'm getting soon a production model (hopefully also a 5D3) for a day or two of testing. Looking forward very much to it.
So far, I'd say the difference in resolution on the D53 vs the D800 might be comparable to that with the AF100 and the Sonys FS100 and F3.
I don't care abut brands and therefore I'll get whichever model wins, but I'm guessing so far the D800 with a Pix220 might be a killer combo for under €4.5k or less (the pix adding pro preamps with true 48v and audio delay if needed, edit-ready 422 prores and an ext TFT for monitoring, all in a single device).
Add a Nikon14-24 and Zeiss ZF 50 and 85/100makro and you're golden.
