I was really hanging on for the D400, but on here folks who already had the D800 gave compelling evidence that the camera would meet most of my needs. As I am as keen on Landscape as Wildlife the decision was slightly easier, although I already had the D700 which was wonderful.
The only area now that I can say the D800 is lacking, but only marginally, is fast moving birds and when panning and keeping in focus. To be fair the UK weather has been a testing time here and bright days are a rarity at present, that said I did manage to get some very satisfactory shots in the Autumn just as I got my D800.
I am looking forward to the spring and really flexing the D800 muscles. However, I have gone from the status of "desperate" for a D400 to"maybe I'll still consider one". At this time I am more interested in the build quality of a DX semi pro and the better balance it gives me with long lenses. I am not a great advocate of the D7000, but that's just a personal issue and does not reflect in it's capabilities.
