I recently got the new Nikon 70-200 f4 lens this weekend. I must say it is a very sharp lens and the new VRiii does a fine job of stabilizing images in low light. I think this is a fantastic compliment to the new Nikon D600. I had the Sigma 70-200 F2.8 EX DG HSM and the thing was just to heavy so i switched. I am not disappointed at all with the newest piece of glass by Nikon. It’s light, sharp and seems to be well made. I will put up some samples soon.
