Canon 15x50 IS Binocular

Outfitted with their proprietary Vari-Angle prism electronic image stabilization system, the Canon 15x50 IS All-Weather Image Stabilized Binocular is an ideal optic for bird and nature watching, marine use, or astronomical use. Its quick-response time and ±0.7° correction angle easily compensates for the common hand-shake that can make viewing through binoculars of this magnification difficult or disorientating. A single-activation button located precisely where the right forefinger naturally rests makes using them easy and allows you to concentrate on viewing without distractions. For increased usage, the 15x50 IS will work as full-featured binocular when the image stabilization is not being used - even if the batteries are dead or removed. Optically, it is built with ultra-low dispersion (UD) glass elements and matching doublet field-flatteners, with their Super Spectra anti-reflection coatings to produce bright and clear high-contrast images without distortion across the entire wide field of view. Protecting the optics and electronics is an armored chassis that benefits from ergonomically-designed grips, and a standard 1/4"-20 tripod mount socket for an even steadier view. Right-eye dioptric correction, twist-up eyecups, and a wide interpupillary adjustment range rounds out the features of this binocular that will become your go-to optic for any outdoor activity.
