Q8 What Makes Canon's IS series so Unique? Eliminated "image shake," which was a major problem with binoculars. Uses the most advanced image stabilizer. Almost everybody who has ever used binoculars at sporting events or concerts has experienced how much the images shake, and you feel that the binoculars are useless. The main complaint of users has been image shake. The higher the magnification, the larger the image shake. In general, any binoculars with over 10x magnification should not be used for a long time. The best solution in the past was to use a tripod. However, tripods are bulky and can't be used everywhere. Even if you need a pair of binoculars of over 10x magnification for bird watching, the most you would want to use since you walk around a lot would be something of 7x or 8x magnification. Canon is the world's first maker to use an active optical image stabilizer for IS series. Because two Vari-Angle Prisms are controlled by a microprocessor, hand shake is eliminated (Fig. 8). As a result, even with over 10x magnification, a tripod is not needed. And they can even be used while viewing from a moving car or train! In addition to the light weight, there is no eye strain to make you tired, so it is possible to use these binoculars for a long time. Vari-Angle Prisms Without shake. Image shake is compensated.
