What they are: as it says, the lightest and least expensive IS binoculars on the market (right now). The optics themselves are only merely very good, but - HAND HELD - with the IS activated, they allow me to read fine print about 20% closer than with my Leica 8x32 Ultras. On a rest, the Leicas are superior. It's the elimination of the jiggles - the 8x25 Canons don't give an image that's as bright and contrasty as those high dollar Leicas, but the steadier image more than makes up for that.
What they aren't: waterproof or armored. So have a care if you use them in conditions of rain or dust. They're much more complicated than simple binocs, with electric circuits inside, and the matter of reliability does come into consideration - but in the first year, they've survived life in the tote bag ,bouncing along dirt roads without a hiccup. Two more things: besides armoring and ruggedizing, Canon had to compromise _somewhere_ to make them this small. So, while the IS deals well with rapid human shaking. it doesn't seem to correct at all for slow motions. I imagine the engineers were forcd to leave off the sensors for slow motions, to fit everything else in. And, they use CR123 batteries, more expensive and harder to find in a pinch than AA batteries. Of course, if the batteries run dead, all your are left with is a functional set of very good, if a bit bulky, 8x25 binocs. What Canon has created is $300 binoculars that - hand held, with the IS active - outperform my high dollar Leica 8x32 Ultras. And, I imagine, the Nikon SE's, too. No kidding.

Whether you are sitting in the nosebleed seats of a stadium or an opera house, with Canon's 8 x 25 IS binoculars you'll get an outstanding close-up view of the action. The binoculars are designed to fit perfectly in your hands and have a rubber coating for nonslip grip and protection from damage. The focus dial is center-mounted and the image stabilizer controls are easily accessible from either hand. Canon's optical image stabilization technology eliminates shake and reduces curvature of field. The image stabilizer operates with a CR123A Lithium battery. The lenses are coated with Super Spectra multicoating that improves image quality by maximizing contrast and minimizing color smear.
Image Stabilization and More With any high magnification binoculars, most users will experience frustrating image shake. Unless fixed to a tripod, image shake can render high magnification binoculars useless. Canon's IS technology is remarkably effective at eliminating this problem and is widely used by the television industry with Canon's professional broadcast quality video recording equipment. A special VAP (Vari-Angle Prism) corrective IS system sits between the objective lens group and the porro prism on each side of the binoculars. Within thousandths of a second of the binoculars being moved from their optical axis by vibrations, a detection system activates the IS mechanism. The VAP shape alters to refract or 'bend' the light path by precisely the right amount, thus fully compensating for the vibration. It is this essentially immediate response that effectively suppresses image shake.
Super Spectra CoatingA number of optical factors affect the brightness of an image, including the amount of incidental light that is reflected by the lens. An uncoated lens will refelect away as much as 8% of the incidentail light, significantly dimming the image. Canon's Super Spectra Coating prevents that reflection.
What do the numbers mean? 15x50? 8x25? The two numbers used to describe any pair of binoculars are their magnification - 8x, 12x, 15x and so on - and the diameter of their objective lenses - 25mm, 36mm, 50mm, and so on. The larger the first number is, the larger the object will appear to be in the objective lens. For instance, if you use a 10x lens and look at an object that is 100 yards away, it appears to be the same size as an object located just 10 yards away. The second number, the size of the objective lens, is important because the larger the objective lens, the more light it can admit for brighter, more detailed images, and the better suited they will be for lowlight situations.
