Indecision is the key to flexibility.

The point of these technologies is to reduce blurriness from camera
shake. If the camera can't shake, the VR/SR/whatever will compensate for
moving subjects, or subjects which the lens/camera thinks are moving.
You typically don't want it to do that.

Yes, for most systems, but the electronic image stabilisation used in
movie cameras and some digital cameras (e.g. for video modes) does rely
purely on the image from the sensor, and therefore could be fooled by
subject movement.

Then the next time your camera is mounted on a tripod, leave the IS on
and see what happens.

That's my point. If the camera's not shaking, then the IS system could
be fooled by moving subjects. That's why manufacturers tell you to turn
off IS if the camera's mounted on a tripod.

Nikon Coolpix 8400 in video mode, for one. It uses what it calls
"electronic VR".

If you make a movie of a group of people walking in the same direction you
can see the VR sometimes moving with the people (so that the people are
steady) and then jumping back (as its stabilisation limit is reached).

Of course, you might call it a movie camera in that mode....
