Canon's 10x30 IS Binoculars deliver outstanding optical performance and unparalleled image stabilization capabilities at a very affordable price. Whether you're sitting in the last stadium row or at the water's edge, you'll get a close-up view of the action with these contoured, lightweight binoculars. The 10x30 IS Binoculars are designed to fit perfectly in your hands. A textured rubber coating provides non-slip grip and protection from the elements, and the center-mounted focus and Image Stabilizer controls are easily accessible from either hand.

What is an Image Stabilizer? The more powerful the binoculars, the more vibrations are magnified. As a result, even a slight shake of your hands will shake the image in the binoculars a lot. Normally, we can tolerate this image shake with binoculars up to 7x magnification. With higher magnification binoculars, the image shake would quickly become intolerable. However, with Canon's Image Stabilizer turned on, the image shake becomes tolerable even at magnifications of 15x and 18x. Such high magnifications were previously unthinkable in a pair of binoculars without the use of a tripod. The Image Stabilizer steadies the image instantaneously and brings out the top-notch optical performance of the lenses.

How does the Image Stabilizer work? The Image Stabilizer suppresses image shake so that the image looks steady to the eye. When the Image Stabilizer is engaged, vertical and horizontal gyros detect motion in any direction. The amount of shake is calculated by a microcomputer and the shake is optimally counteracted by either a set of Vari-Angle Prisms or a Tilt mechanism, in effect,the light's refraction is altered so that the image always looks steady to the eye.
