If you’re shooting sports with a Nikon D3, D700 or D300, you’re probably shooting fairly often in high-speed continuous mode, so you want the best performance (most number of frames per second) possible.
Well, if you’re shooting with a VR (Vibration Reduction) lens, once your shutter speed gets above 1/500 of a second, you should turn VR off to avoid any shutter lag or slower frame advance rates caused by the VR trying to stabilize the lens. (At high shutter speeds, you don’t really need to VR—after all, Vibration Reduction was designed to let you hand hold in low light, slow shutter speed situations. If you’re shooting with shutter speeds above 1/500 of a second, you really don’t need the VR, eh?).
When I’m shooting sports, to freeze action, I generally want my shutter speed to be at least 1/1000 of a second (or faster), so I know at the beginning of the shoot to turn my VR off. Anyway, I thought that might be helpful to other Nikon sports shooters out there. (Photo above by Eric Kuna).
