I've always been interested in the D3 but had to settle for the D700 sometime early last year. After months of figuring out how to get the best out of the D700, I would have to say that it's one very good camera. My recent trip to the US and Canada was well covered with the D700 and I did get enough photos to satisfy me for a long time. However, there is always this craving for the D3 that never goes away. I have seen reviews by Thom Hogan of the D700 and the D3 and am wondering if I am missing out on anything in sticking out with the D700. As I now have some spare dollars for the upgrade, is it truly worth the effort to go up the ladder (so to speak). I have the 24-70 and the 70-200 f/2.8 VR2 lenses that I think are enough for my needs at the moment and which I know are also perfect for the D3. The only thing that is probably annoying about the D3 is the lack of a built-in flash (the SB900 is a monster with any DSLR) but the 100% viewfinder is something crucial (I did find the less than 100% view on the D700 an issue as I had some photos with unwanted objects and people in the final frame). I've seen the review by Thom of the D3s and would have to say that the D3 may be of more use to me than the newer model. In all, could anyone help out? Thanks.
