Canon Image Stabilized 8x20 Overview

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 versatile and compact. They compensate for hand-shake which makes them ideal for a long day of birding, nature watching, or attending your favorite sporting event. The Lens Shift Image Stabilization eliminates possible shaking made by movement and vibration with 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' 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' field of view at 1000 yards
  • 3-element / 2-group objective lens design
  • 4-element / 3-group eyepiece lens design
Image Stabilization
  • Choose Normal IS or Powered IS to deliver the correct performance depending on whether the subject is moving or still
  • Makes it easy to maintain a high-magnification view, especially in situations where body movement or strong shake might occur
  • Lens Shift Image Stabilization system is effective in canceling out shaking made by movement and vibration
  • Incorporates a continually adjusting vibration gyro mechanism that moves IS lens both vertically and horizontally
  • Simple push button delivers up to 5 minutes of continuous operation

Canon Image Stabilized 8x20 Reviews

Very good for their size

These are very lightweight and convenient. The field of vision is small, so maybe not great for a beginner. Standard birding binoculars are 8x42. That said, the image stabilizer feature is great! I’m 75 and a lot of us at this age are less steady than we once were, and this helps enormously. And they are affordable!

Generally better than expected!

I bought these as a Christmas present mostly for my wife (thus the smaller version/lighter weight) because of the frustration I've observed with her use of lesser products. She has never experienced the joy of large aperture, flat field, pro optics. Combined with my decades-long experience with Canon's vari-angle prism I.S. tech and their follow-on technologies, I KNEW if purchasing something this expensive, I would do it from Canon. I am not at all disappointed in this product: If I were buying JUST for me, I would have gone with with one of their more expensive models with higher magnification AND a larger aperture primary lens. Focus is crisp, easy, very flat across the field of view, and then when holding the IS button, the stabilization is so obvious and clean it makes me wonder if I need to see a doctor about hand tremors... () It was especially gratifying to watch my wife use them the first time and notice how easy it was to focus on objects of varying distances. Then as a I told her to spot a more distant object, she was able to frame it, and describe the details to me. It was here where I introduced her to the IS capabilities by having her hold her view steady while letting me guide her finger to the stabilizer button. Her reaction was priceless... I also bought (for me) a tripod mounting kit and a smartphone adapter for an eyepiece. CANON SHOULD INCLUDE LENS CAPS, even if as an extra cost option. Depending on aftermarket parts for this critical piece is short-sighted {see what I did there?} at best.
