I was amazed at the really slow shutter speed and handheld you took these pictures at. I guess the VR was a great help. I can see the man's hand moving is one shot. It makes me feel a lot better about the camera all around and not having to use a tripod all the time. There was another post that used the Nikon 28-300mm lens that took some great pictures too, so that show you don't have to have the best lens to get some great pictures with this camera. Not that the 28-300mm is that bad of a lens, but at least you can use some of the cheaper lenses.
Like to see one of your RAW pictures when you take one, and maybe at f8 to see how they look.
