Canon makes several image stabilized binoculars. The only ones (as far as I know) with "luxury" (L) glass are the Canon 10 x 42 L IS.
I own these and LOVE them. Years ago (early to mid 1990's) I tried several pairs of binoculars at Camera Corner. They stocked at least one pair of Canon image stabilized binoculars. Even then I really liked the image stabilization, but the image wasn't good enough for me (even with image stabilization--I remember thinking at the time that it was too bad that Canon didn't offer an image stabilized binocular with better optics). I also tried a pair of Zeiss and those had field curvature, which I found quite annoying, particularly at that high price point (well over a thousand dollars at the time, as I recall). I tried a pair of Nikons (in the 300-500 dollar range, as I recall) and wasn't impressed. I ended up with a wonderful pair of Leica Trinovid 10x50 BA binoculars. Their image is almost flat and sharpness is stunning. They are, however, quite heavy and difficult to hold still. Also these Leicas have no tripod adapter.
Fast forward a few decades. I had read several people's description of the Canon 10 x 42 IS binoculars and bought a pair. I'm extremely happy with them. They are flat across the field and their color correction is excellent. Comparing back and forth, they are extremely similar in image quality to my Leica Trinovid 10x50 BA binoculars, and based purely on the image quality, it's impossible for me to say which I like better. But the image stabilization is an absolute game changer! I've thought about getting Swarovski EL 10 x 50 binoculars or some other alpha binocular, but the image quality of the Canon 10 x4 2 L IS is really excellent. If they weren't image stabilized, they'd still be excellent, but with image stabilization, they're awesome. And even with the luxury glass and image stabilization, they're still cheaper than many of the alpha binoculars which don't have image stabilization. Based purely on the optics, they almost certainly wouldn't be as good a pair of Swarovski EL 10 x 50 binoculars, but I couldn't say how close they'd be. Someone who could tell you that is Tamiji Homma (post #23) who owns them both. But the image stabilization makes them easier to see through and (I would contend that) it's reasonable to factor this in when comparing their optics to the optics of other top tier binoculars, especially since these are cheaper than many of those other "alpha" binoculars. (I don't understand why Swarovski doesn't make an image stabilized version of the EL 10 x 50 binoculars. I'd be willing to pay a LOT for a pair of those. But they don't.)
Bottom line: I'd very highly recommend the Canon 10 x 42 L IS. They aren't that heavy, even with image stabilization (lighter than my old Trinovids which don't have image stabilization). For a comparison with the other top dogs, I'd ask someone like Tamiji Homma (post #23) who owns several of them, including the Canon 10 x 42 L IS and the Swarovski EL 10 x 50 binoculars.
One other thing to reiterate: Although Canon makes several different image stabilized binoculars, the only ones (as far as I know) with "luxury" (L) glass are the Canon 10 x 42 L IS. (I haven't bothered to look at any of their other image stabilized models based on my past experience with one pair in the early to mid 1990's--I don't know whether any of their current models [other than the 10 x 42 L IS] are any better now than those were then.)
