How does the VRII work?

The highlight of AF-S VR Zoom-Nikkor 70-300mm f/4.5-5.6G IF-ED is the benefit of improved Vibration Reduction (VRII), an innovation that makes it possible to take substantially sharper handheld pictures at slower shutter speeds than would otherwise be possible. With the new VRII advantage, users can take pictures at shutter speeds as much as 4 stops slower* than they ordinarily could shoot without camera shake with a non-VR lens! Examples below show you how the VRII works in actual shooting.
