Building on the success of their larger IS binoculars and borrowing the Lens Shift Image Stabilization from their EF lenses, Canon's 8x20 IS Image Stabilized Binoculars are a versatile and compact optic that compensates for hand-shake to make them ideal for a long day of bird-watching, nature-watching, or enjoying your favorite sporting event. The Lens Shift Image Stabilization 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 stabilization 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 binoculars run on one included CR123 battery. Designed for portability and ease-of-use, they measure in with a compact length of well under six inches and weigh significantly less than a pound.
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
- 6.6-foot minimum focus distance allows detailed observations of small birds, bugs, flora & fauna at close range such as at feeders, flower beds, or window boxes
- 346.5-foot field of view at 1000 yards
- 3-element / 2-group objective lens design
- 4-element / 3-group eyepiece lens design
