The Canon 15x50 IS All-Weather is an image-stabilised binocular for bird and nature watching, marine use or astronomical viewing, using Canon's Vari-Angle prism system to correct for hand-shake by up to ±0.7° with a quick response time. A single activation button sits where the right forefinger naturally rests, and the binocular still works as a standard non-stabilised optic if the two AA batteries are flat or removed.

Optically it uses ultra-low dispersion glass elements with doublet field-flatteners and Super Spectra anti-reflection coatings for a bright, high-contrast, distortion-free image across a wide apparent field of view. The body carries weatherproof, slip-resistant armour with fold-down rubber eyecups, a large centre focusing knob and a standard 1/4"-20 tripod socket.
