Frankly, for such a purpose, I would recommend the Nikkor AF-S 28-300mm f/3.5-5.6G ED VR for the D700. It has the flexibility of focal range and with the D700 the (relatively) slow lens is not a problem. Just boost it to 6400 and you have all the speed you want. I have several friends who use the lens and have nothing but good to say.
