I want to get a 24-70 f2.8 lens. The Tamron appealed to me because of the VC which the others don't have but it is impossible to buy with a Nikon mount at present and nobody can say how long before they are available. Do I need VR. I have taken 2 photos at 70mm with my 70-300. The first is with VR off, the second it is switched on. I shot in Jpeg with the same settings and only added the same sharpening in PP and then resized. There is a slight breeze here at present but I hope I got these between small gusts.
