Canon's third generation12x36 IS III Image Stabilized Binocularsfeature 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.
- Vari-Angle Prism Image Stabilization
- Eco-Friendly Lead-Free Glass
- Super Spectra Multicoated Optics
- Doublet Field-Flattener Lenses
- Apparent Angle of View: 60
- Center Focus Wheel
- Runs on Two AA Alkaline / NiMH Batteries
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 77F (25C). Designed for portability and ease of use, they measures in with a compact length of 127mm and weighs just over 660g.
