I have always followed Nikon's recomendation of turning VR on, when using a monopod. Until now, this has yielded good results. This afternoon, I decided to take a few shots of birds and squirrels, in my back yard. I was using the 70-200, with TC17, on a monopod. Per usual, I had VR turned on. As I was preparing to go into the house, and had the camera removed from the monopod, I noticed some interesting birds, and grabbed a few shots hand-held, at 340mm and 1/60 second. When I viewed the shots, none of those taken with the monopod were sharp; and, the few taken hand-held were much sharper. Has anyone else experienced similar results?
