Not so long ago, Nikon users had to weigh up the pro and con's and agonize over the best zoom option. I went for the DX specific 17-55mm f/2.8G DX and 12-24mm f/4G DX.
With the advent of the D3, it was an easy choice and I went with the 24-70mm f/2.8G and 14-24mm f/2.8G. I don't do a lot of ultra wide angle work but when I do, the 14-24mm is impressive. It doesn't take screw on filters but the results are worth while.
