Some have the function built into the body so it will work with any lens and some lenses have vibration reduction built in. The movement is intended to counteract an unwanted shift, so in theory it is preserving, not cutting off any image data. The Leica systems don't do it because their approach is to position the sensor at the focus plane as perfectly as possible, adjusted to a couple of microns increments. So the sensor is intended to record exactly what went in, if you like, not help compensate for imperfect conditions/technique. None of the medium format systems use that sensor shifting either. Different philosophies, which is not to say that each doesn't work.
