When I got my D200 or D90 I also got an 18-200 DX lens. Not that it was better, but because it was cheaper and lighter for trips and hikes. Later I replaced that with the superior 28-300 FX lens. In the end, my last DX lens was the 10-24 because there was no FX equivalent.
Now that I have a V1 (CX), I no longer have any need for a DX camera. I do not even try to shoot little birds in flight so I do not have any glass longer than the 80-400 either.
