How about the 16-85mm f/3.5-5.6G ED VR instead ? I had the AF-S NIKKOR 24-70mm f/2.8G ED and I used it on my D300, but I liked the 16-85 much better. Not only because of the weight, but because of the quality too. My 16-85 was just better than the 24-70 which I had. First I thought there is something wrong with the 24-70. I send it to Nikon. But the lens came back with the statement from Nikon that it is "within its specs". So, I sold it and kept the 16-85. I assume it had to do with this particular version. If you read the reviews on the net, all other photographer seam to be happy with the AF-S NIKKOR 24-70mm f/2.8G ED. Assuming you don't use a FF camera I think you can't go wrong with the 16-85mm f/3.5-5.6G ED VR.
