Are you saying you have never used a D800?
No didn't say that, but never extensively. Someone had one on set, I carry our Nikon glass usually F for one RED1 but the newer G for the Scarlet if needed as backup as I use PL for the other red one and Canon mont for the scarlet., so anyway I tossed a g lens on a d800 and shot some with led and with hmi.
I won't buy a d800, doubt any Nikon, I just fight the color too much.
I didn't like it, but I don't like new Nikon G glass, though I love the 200 F2. That lens is magical and much nicer than Canon's version.
Honestly I can't tell you which cameras I like right now*, because I'm tired with working huge hours.
*Actually not true. It's taken me 6 months to understand the oly em-5. That may sound stretched but since the camera is a lab, the processor is a lab, combining the two you end up with a million settings and the olympus is sensitive.
I've done some stupid in store testing with the Sony A7 and the Olympus twice and both times the olympus produced a better file and better look, though that's stupid in store testing.
I think I now have the olympus to look as more like my m8 as any cmos camera can.
I was predisposed to buy an A7 or two since I have two zeiss A mount zooms (which I like) but regardless of what I do, the A7 file doesn't hold up in look as well as the Olympus (I know that makes no sense given the size) and it seems to have a lot of shutter slap or blur. Kind of dissapointing but once again, this is stupid in store testing.
