The high-magnification Canon All-Weather Binoculars 15x50 IS AW with optical image stabilizer offer professionals and demanding amateurs innovative technology that sets performance standards. The optical image stabilizer is based on a novel variable-angle prism and ensures a steady image. This allows these binoculars to be used effortlessly from hand, as well as from vehicles or boats. The shake-free image not only makes the finest details clearly visible but also enables fatigue-free observation. Special field-flattening lenses eliminate the typical distortion and blurriness at the edges of the image found in high-magnification binoculars. An unusually large field of view for high-magnification binoculars and the 15 mm exit pupil located behind the eyepiece further facilitate observation.
