Loving my D800 as well and the video is superb up to ISO1600
Didn't you just sell your D700 and all your lenses to go mirrorless? Have you bought some new lenses or did you have some left over?
Have had some time last few days to play with the D800E .... still yet to come across a photograph where moire is visible. Yes, I'm sure it's going to happen at some point, but I really think it's not going to be as major an issue as people in some quarters have made out. Absolutely no regrets at choosing the D800E over D800 here.
Maybe this is useful DP?
