I showed a fine print of some flowers I took this summer using D2X or D2Xs and my 28mm 1.4D. A nice woman from Russia said in her accent, wow, it looks done by a professional. I said thanks, that's what I want to hear. Another co-worker said, are you sure this is a photograph to a team member I gave a print to for Christmas? It looks so artistic, so well composed, he can "definitely sell this one" he said.
So, obsolete? I hardly think so. The D2 series takes as good a images as it ever did. At 100 iso in good light, it's almost untouchable still in my mind with the right post processing. But there are alternatives now. The D3 will also fill many gaps we could not fill before. The D300 will fill some gaps. These tools will hold me maybe until a D3X is sour grapes in the folks hands that have to have the latest. Then, the D2 series will probably still be cranking them out for me too. I can't possibly stay with every generation, so I will disappear from the forums when the D3X comes out, and use the many tools I already have at that point and work on creating some art.
