Canon 10x42 IS L Waterproof Binoculars

Outfitted with their proprietary Vari-Angle prism electronic image stabilization system, the Canon 10x42 L IS WP Image Stabilized Binoculars are an ideal optic for bird and nature watching, marine use, or astronomical use. Their quick-response time and ±0.8° correction angle easily compensates for the common hand-shake that can make viewing through binoculars of this magnification difficult or disorienting. A single-activation button located precisely where the right forefinger naturally rests makes using them easy, and an optional 5-minute activation mode allows you to concentrate on viewing without distractions.

For increased usage, the L IS WP will work as full-featured binoculars when the image stabilization is not being used, even if the batteries are dead or removed. Optically, they are built with ultralow-dispersion (UD) glass elements and matching doublet field-flatteners, with their Super Spectra antireflection 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. Tethered front and rear lens caps, right-eye dioptric correction, twist-up eyecups, front filter threads, and a wide interpupillary adjustment range rounds out the features of these binoculars that will become your go-to optic for any outdoor activity.
