"VR is an artificial means of stabilization. In order to eliminate or reduce any kind of blur in a photo, the camera must be stabilized (not moving) from oscillating or up and down movement. A tripod provides this stabilization. It is a fixed base. A monopod prevents up and down movement, but allows side to side movement, which does not need VR stabilization. Therefore, it is wise to shut off VR when on a tripod and/or monopod." —Jack
Hi kiwi86,
Yep! that's what is! This VR feature was thought, originally, for people with motoric
disorders or if the photographer is subjected to steady vibrations such as in a car i.e.
The price to pay for this stabilization is the loss of the instant. This means that, when
one presses the release, the real take will happen only when the camera system will
have obtain sure focus. If you press the release, keep the pose until the shutter is
released!
This loss of the instant makes, for me, VR a most undesirable feature.
