I've been trying to get an idea about a good alternative to my 16-85VR as I struggle to get good sharp images out of it - at least it is definitely not sharper than my old 18-105 was and so I need a few suggestions from yous guys. I am really tempted to buy the Sigma f1.8 but it has no VR and I have the shakes a bit too much. If I look at the 16-35VR f4, the DxO Mark results on a D7000 indicate it is no better than the 16-85 that I have which is not much use. I would probably get better results from it that my 16-85 if the VR is as good as the 24-120's VR though (anybody know if it is the same?). The 17-55 f2.8 looks useful, but again it has no VR.
Ideally, I would like a D610 and 24-120, but I can't run to that, so what suggestions or sage advice do you guys have?
