When I had the chance, to buy one of these lense for D3, it was a tough choice. Simply enough: a new 16-35 = a nice used 17-35. I picked the former one due to the weight I think, and some rumour sayingthat 16-35 is sharper than 17-35 because it is quite new, which is reasonable. There is some distortion, but I don't care since it can be subtle and fixed anyway. I used 16-35 today to shoot outdoor buildings and indoor events (very dark!), as well as some night scene. I think it is quite handy! As an extra, I think it can focus very closely to the object, which is very useful if there are lots of people walking around you. The VR I think help a lot when you are in dark/night situation, when you need a wide angle. Since I was not looking for shallow DOF, F4 is completely fine. I am processing the pictures now, so I am wondering if the quality/sharpness of the outputs is good enough in real world, compared with 17-35. Since this 16-35 is quite new, out of curiosity, I want to ask this A VS B question to see how it is accepted. (As for the application, for me, as I mentioned, indoor/outdoor/macro discussion is appreciated.) Thanks!
