Thought I'd share this for anyone considering this lens. I picked up the Sigma 120-400 from the FM forums for $600 so I can have a zoo/moon shot lens that can reach further than my 70-200. My D7K is on it's way back from Nikon HQ in New York so I used the D700 when I went to the zoo yesterday. I'm very happy with the results and for the price I'm very happy with the purchase and would recommend this lens to anyone wanting a longer reach.
