I'm planning to pick up a second FX body early next year and I'm trying to decide between these two. I'm currently using a D700 which I plan to keep. I like the interface and controls of the D800 which is the same or similar to my other camera bodies and that could be a factor. I also like cf cards and being able to change apertures in LV. On the other hand, saving $900 means I could pick up a 24-120 VRII to replace the 24-120 VR kit lens. So I'm interested in hearing from users that choose between the two. BTW, I enjoy macro, scenics and landscaspes and sports. I'd use the D700 for the higher fps for sports so that isn't a concern.
