With the arrival of the D600, and all that entails, I decided to bump up this old thread.
When I started it, the D700 seemed utterly magical compared to my DX cam.
But I struggled to explain why.
A year or two has now gone by and I've learned a lot, changed a few things, but a lot of things have gone unchanged.
For example, I've stopped using the 24-120 VR (or the 24-120D) with the D700. (Anyone want to buy these- nothing wrong with them, but I use the 300s and other lenses for everything else), I've also avoided using the 700 for telephoto work as the DX cam does it so well.
However, the 700 & 16-35 VR combo just continue to amaze me. The camera seems to put more light on the pic than my eye can see. It's hard to put 'your finger' on it, but the 700 pix are truly different. FWIW, I think Nikon are on to a winner if they try to bring more folk into FX. It's clearly better, even if it's hard to say exactly how.
