I bought the Nikon 24-70 f2.8 for my new D700 and I am very happy with it. It produces very sharp images with very good color and is excellent in low light. Many reviews rate this lens as one of the sharpest the reviewers have every tested. The only downsides are the weight of the lens and the cost. It is heavy and expensive. In spite of this, I highly recommend this lens for use with the D700.
