Image Stabilization
Image Stabilization (IS), also called vibration reduction and anti-shake, minimizes or prevents digital images from becoming blurred due to camera shake. First used in camcorders, Image Stabilization is becoming a standard feature on an increasing number of digital cameras.
IS was initially used on consumer digital cameras with long telephoto lens. Now it's not uncommon to find it on cameras with a 3X zoom range.
IS helps prevent camera movement due to slow shutter speeds, when using a telephoto lens and when taking macro shots. It does not, however, steady the effect of a moving subject.
Optical Image Stabilization
Don't be fooled by claims that a digital camera has image stabilization but it simply automatically increases the ISO. A camera with hardware based Optical Image Stabilization produces the best results.
If your camera had Image stabilization, it is best to keep it turned on at all times. The only exception, as recommended by manufacturers, is to turn off IS when using a tripod or other camera support.
Digital cameras with Optical Image Stabilization can have up to three modes: Continuous, Shoot Only and/or Panning.
