CPN Explains How Image Stabilization Works

If you've ever wondered how image stabilization works in Canon lenses, you're in luck! The Canon Professional Network has published an Infobank article on Image Stabilization.

From the Canon Professional Network:

Camera shake is the thief of sharpness. If you are hand-holding a camera and lens, they will move as you press the shutter release. Movement during exposure blurs the image.

Much of the time, you will not notice the effects of camera shake. If you are shooting with a fast shutter speed or a wide-angle lens, the blurring may not be significant- but it will still be there, and might appear if you have a big enlargement made from the image.

The only way to overcome camera shake is to eliminate the movement of the camera and lens during the exposure. The obvious way to do this is by taking the camera out of your hands and fixing it to something that will not move, such as a photographic tripod. However a tripod is only effective if it is sturdy, which usually means heavy.

Fortunately, Canon offers another method of reducing, if not eliminating, the effects of camera shake. Image stabilised lenses, first seen in 1995, approach the problem laterally. Rather than trying to stop the movement of a hand-held camera, they seek to introduce an opposing movement within the lens. The aim is to keep the image static on the sensor or film, despite the movement of the camera.
