The D3x isn't the same sensor as the D700/D3 so it doesn't really apply to quazi's statement.Originally posted by Gibson
The D3x has ridiculously detailed images for anyone doing studio work, and the D3 and D3s have a four FPS advantage over the D700 right of the box. As well, they have the below advantage:
But on the other side of that, with the D3 you also get dual card slots, and an upgraded buffer, a battery that lasts WAY longer than the D700 normal batteries(I shoot about 2000 pictures on a single charge, vs 1200 on the normal size batteries), the integrated portrait shooting button, and I'm sure one or two other things.
I know the D700 with the grip gets a portrait button too, but the D3 body is actually smaller than the D700 with the grip by a bit.
