Building on the success of their larger IS binoculars and borrowing the Lens Shift Image Stabilisation from their EF lenses, Canon's 8x20 IS Image Stabilised Binocular is a versatile and compact optic that compensates for hand-shake to make it ideal for a long day of bird-watching, nature-watching, or enjoying your favorite sporting event. The Lens Shift Image Stabilisation cancels possible shaking made by movement and vibration by incorporating a continually adjusting vibration gyro mechanism that moves the IS lens vertically and horizontally. With the choice of either Normal or Powered IS options, you can choose the right mode for the situation to deliver the best performance.
Beyond the image stabilisation performance are optical features that improve image overall image quality. This begins with Canon's antireflection Super Spectra Coating system to reduce light loss and improve image contrast across the entire visual spectrum. Next, they employ a Porro prism optical path that provides a rich depth of field to enable users to better judge distance between objects while delivering a wider field of view versus similar roof prism models. A field-flattener corrects spherical aberration for distortion-free views, especially at the edges. The binocular runs on one included CR123 battery. Designed for portability and ease-of-use, it measures in with a compact length of well under 15cm and weighs significantly less than half a kilogram.
Optical Performance
Moderate 8x magnification brings objects in close for observation while helping to maintain a generous field of view and wider exit pupil versus high power options
20mm objective lenses helps to maintain a compact form factor for easy packing, carrying, and handling
Porro prism optical path provides a wider field of view versus roof with a rich depth of field for an immersive 3D visual effect
Field-flattener lens system corrects distortion and spherical aberration for crisp views, especially at the edges
Broadband Super Spectra Coating system reduces color bias, lens flare, and ghosting to deliver sharp views with improved contrast and accurate color across the entire visual spectrum
2 metre minimum focus distance allows detailed observations of small birds, bugs, flora & fauna at close range such as at feeders, flower beds, or window boxes
100m field of view at 1000m
