If you’re really shaky, don’t use a tripod, and want small binoculars, then these are still for you. If you’re one of those people or if you tend to use a tripod for stabilization, you may not need either of these Canon IS models. Many users are able to hold small binoculars steady enough against the face that they don’t need the image stabilizing afforded by compact binos like these. But if what you really want is compact binoculars, you know that fact going in and are satisfied with the image you get. You need larger objective lenses to let more light in to get a better picture. With the objective lenses on the small side at 20 millimeters, you’re not going to get the best optical performance with these binoculars, especially under low light conditions. However, if you’re like me and never take your optics out in the rain anyway, this really doesn’t matter for you. These binoculars are not waterproof – or any kind of proof, for that matter. These Canon optics have “ Super Spectra Coating” (Canon’s special phrase for something many companies use) to “suppress reflected light across a wide range of wavelengths.” What this means for you is that you get as clear an image as Canon knows how to give you. Some binos will show you things called color bias, as well as lens flare and ghosting. This technology compensates for that, giving you a completely focused picture of your target. Normally, a curved lens blurs the image around the edges. These Canon binoculars both use a field flattening lens to give you sharper images all the way to the edge of the circle. Inside the Canon IS binoculars Flat Is Good Bias Is Bad There is a special lens inside that will move to compensate for any shaking of the binoculars as a unit. To take full advantage of the stabilizing property, you press an IS button that will activate the innards for up to five minutes at a time. You simply can’t get away from the fact that you need to include the battery to take advantage of the image stabilizing feature of your binos. The fact remains that, as of this writing, these are one of the lightest pair of IS binoculars available. So then, it’s not really all that big of a deal either way. I assume this means there’s some pair of binos out there in birding land that weighs a fraction of an ounce less after you insert the battery into your Canon IS 8×20. 5 Conclusions about the Compact Canon IS BinocularsĬanon maintains that these new image-stabilized binoculars are the world’s lightest – lightest that is, if you don’t include the required battery.4 Specifications of the Canon IS 20mm Binoculars.
