Hi, the fuss is about finally getting the digital equivalent of F100. I "upgraded" my F100 to a D100 when the F100 still had sex appeal and high resale value. Subsequently I traded that for a D200.
I skipped the D300 completely because it did not offer enough benefits over my D200. I lusted over the D3 but as a happy snapper the $5k could not be justified. I'm glad I waited the 6 months, because now Nikon has really something special in the economy class too. The D700 is warmly welcomed. I will keep my D200 too, though I expect the poor fellow to be sitting on the shelf most of the time.
I only have 2 DX lenses and 11 FX ones. Most likely the DX ones will be for sale before year's end. Do I need to say more?
