There are three VR modes selectable according to shooting situations. VR lenses are divided into three groups — with Normal mode only, with Normal and Active modes, and with Normal and Tripod (tripod vibration reduction) modes.
Tripod mode of Nikon's VR (Vibration Reduction) system is most recommended when a tripod is used. It is often thought that image blur caused by camera shake can be prevented by using a tripod. Actually, however, even using a tripod may result in image blur because of tripod vibration caused by mirror or shutter movement at the time of exposure.
This mode automatically differentiates the frequency of the vibration from that of camera shake, and changes algorithm to correct image blur caused by slight tripod vibration. Tripod mode is employed in three super-telephoto lenses that are likely to be used with a tripod.
The following lenses employ the function that detect tripod vibration and automatically reduce the effect. (Tripod mode switch is not equipped)
