Even if jittery shooters don't get 5 stops out of the VR, they would most certainly be the group that benefits the most. I know if I'm tired or hungry, I end up increasing the shutter speed to make up for the jitters. I have been amazed at how well the VR works on this lens. The only thing I've noticed on the negative side is that when I pick up and shoot very quickly, it seem that sometimes the VR didn't kick in in time resulting in a blurry shot. Could be just me giving a shake that no current VR can handle.
