I received my 55-200mm DX VR lens yesterday and have been playing around with it. The attached photo reflects what I am seeing. All shots were taken at 200mm while varying shutter speed and turning the VR on and off. The improvement at slow shutter speed (50 second) shows dramatic improvement but at higher speeds thw VR seems to actually degrade things. So it would seem from this one time very inexact test that one should only turn the VR on under lower light conditions. I'm curious if others have experienced this or should I do some more extensive investigation.
