Canon 12x36 IS III Image Stabilised Binoculars

Canon’s third generation 12×36 IS III Image Stabilized Binoculars feature the proprietary IS system adapted from the lens systems to create this compact optic that compensates for hand-shake to make them ideal for a long day of bird or nature-watching and sporting events. Utilizing Vari-Angle prisms placed between the front lens and the main prism, when the internal gyro sensors vertical or horizontal detect movement they direct the prisms to compensate and correct for external the shaking to produce smoother views and panning. A microcomputer, outfitted with proprietary algorithms, enhances IS operation, aids shorter startup times, and enable more efficient energy consumption. Beyond the image stabilization performance are optical features that improve image overall image quality. This begins with Canon’s anti-reflection Super Spectra multicoatings to reduce light loss and improve image contrast. Next, they employ a Porro prism optical path that provides a rich depth of field to enable users to better judge distance between objects and a comfortable long 14.5mm eye relief. A doublet field-flattener corrects spherical aberration for distortion-free views, especially at the edges, and wide angle 60° apparent angle of view deliver a truly immersive observational experience. The binoculars run on two included and readily available AA batteries that will power the binoculars for up to nine hours at 77°F. Designed for portability and ease-of-use, they measures in with a compact length of 6.9” and weighs just over 23 oz. 12x magnification 36mm objective lenses Porro prism optical path Doublet field-flattener corrects spherical aberration for distortion-free views, especially at the edges Eco-friendly lead-free glass 262’ field of view at 1000 yd 60° apparent angle of view 2-element / 1-group objective lenses 5-element / 4-group eyepiece lenses ±0.8° stabilization freedom Vari-angle prism image stabilization system uses a combination of gyro sensors and microprocessor to adjust the angle for stabilization Specs: Prism Type Porro Performance: Magnification 12x Objective Lens Diameter 36 mm Angle of View 5° (Actual) Field of View 262’ 1000 yd / 86.98 m 1000 m Minimum Focus Distance 19.7’ / 6 m Exit Pupil Diameter 3 mm Eye Relief 14.5 mm Interpupillary Adjustment 55 to 75 mm / 2.2 to 3” Diopter Adjustment 3 to +3 Focus Type Center Features: Stabilization Freedom +/ 0.8° General Battery 2 x AA Dimensions 6.9 × 5 × 2.8” / 17.53 × 12.7 × 7.11 cm Weight 23.3 oz / 660 g
