Sorry, but the 24-120mm, even the new one, just isn't as competent as one could wish.
Neither is Nikon's 24-70 f/2.8G. It's actually a fairly middle of the road lens.
My experience is that the Tamron 24-70 f/2.8 DI VC is a far better lens, and most technical reviews confirm this. It also is a stabilized lens, which of course the Nikkor isn't. Costs around $1100-1200 US. Excellent value, and likely the best 24-70mm f/2.8 on the market, except for the new Canon 24-70mm II, which is twice the price and regretably won't work on a Nikon.
