Canon 18 X 50 IS All Weather (AW) Image Stabilized Binoculars
|Minimize Shaking, Maximize Viewing.
Shaking occurs naturally when you hold binoculars for an extended period of time. Wind, muscle fatigue and even excitement can contribute to "binocular shake". The more powerful the binoculars, the more pronounced the shake appears. It's tiring on your eyes, it's distracting, and it makes getting a good, sharp focus simply impossible. To solve this common problem, many Canon binoculars are equipped with Image Stabilizer (IS) technologies. Originally developed for Canon's high performance video camcorder family, these IS technologies have been brilliantly adapted specifically for Canon's binocular line.
It isn't always convenient to use a tripod - especially if you or your subject is moving. With Canon's IS binocular models, there's no need for additional equipment. Canon offers an Image Stabilizer system utilizing a Vari-Angle Prism (VAP) on the 18 X 50 IS AW Binoculars. This system has two sensors - one vertical and another horizontal - that detect motion as well as a microprocessor that adjusts the Vari-Angle Prism on each side, in a bellow-type fashion, according to the amount of binocular shake detected. This provides instant adjustment of the refraction angle to compensate for motion. So what you see through the lenses is absolutely steady - even when you're not.
Each Canon binocular has been engineered to deliver performance that will impress. The state-of-the-art optical technology from Canon's world-renowned EF Lens series has been carefully adapted especially for use in several Canon binocular models, offering unparalleled resolution. Also, Super Spectra Coating increases image contrast and reduces lens flare and ghosting in most Canon binoculars. In addition, Canon uses aspherical elements in several of its designs to assure sharper focus while dramatically cutting distortion. Technologies like these enable Canon binoculars to perform at an extraordinarily high standard.
These all weather binoculars set a new performance standard. With one touch Image Stabilizer technology, they instantly compensate for "binocular shake." Large diameter 50 mm front objective lenses accommodate a wide range of activities, from sports to astronomical observation of brighter objects. A multi-coated Ultra-Low Dispersion (UD) lens element in each objective section delivers outstanding image contrast, sharpness, and color clarity. To accommodate eyeglass wearers, 15 mm Long-Eye Relief provides greater viewing comfort, and the ergonomic design makes them very easy to hold. An optional anti-fog eyepiece prevents condensation and fogging in foul weather.
