I've used these binoculars for astronomy and bird watching for about 2 weeks. They are outstanding, even without using the image stabilization. It's remarkable to experience how jitter vanishes when the stabilization is engaged: the moons of Jupiter pop out, and central peaks within large lunar craters are easy to see.
The most interesting effect of the image stabilization occurs in dynamic scenes, where bushes or trees may be moving in the wind (and perhaps a bird or other creature hidden there as well). Without the stabilization, jitter makes it impossible to identify details in such scenes. The stabilization function really reveals much in such instances, since the observer's random motions are canceled out.
The quality of construction is excellent; the focus mechanism is silky smooth, and has a considerable range; the field of view is very good; and the optical correction is outstandingly sharp over the entire field.
Buy a couple of snap-in 58 mm lens caps to protect the front optics, you don't need anything else; Canon E-58U caps(for about $8.50) work fine.

These great binoculars arived just a few days after I ordered them.
I've been enjoying them ever since. The image stabilazation is awe inspiring. It cuts down on eye fatigue as well. They are a bit on the heavy side, but thats to be expected.
Listed as frequenty bought together are,
Canon E-58U 58mm Snap-On Accessory Lens Cap
Tiffen 58mm UV Protection Filter
I ordered both assuming they were a good idea as there are no lens caps for the large lenses. Neither Item fits.
Update: after recieving a comment about the filter and lens cap, I took another look, (this time with my glasses on) the filter does indeed fit. And the cap clips right onto the filter. Be sure and order 2 of each. My apologies for the mistaken info, and thanks for the correction, as I now have lens protection:)

Most of the reviews I see for IS binoculars are by and for plane spotters and other non-birders, so I wanted to add the wildlife viewing perspective to the mix.
I have owned 2 different pairs of the 12x Cannon IS Binoculars, one pair of the 15x Cannon IS binos and I have tested the 10x42 L series (high-end, geared towards birders). I will cross-post these comments for all three. For any of you birders out there trying to decide which is the right choice for you, here are my observations.
First, general comments that apply to all three:
1) Image stabilization is great! There is nothing not to love about it. Why all birders on earth don't use these things is a mystery to me. For the money, I would prefer to spend an extra $200 on image stabilization vs spending an extra $1000 for a comparable improvement in optics quality.
2) These binoculars are heavy and bulky. The grip, the feel and the ease of use are different than those of "normal" high-end binoculars. The human factors of the engineering range from acceptable (12x) to incomprehensibly bad (10x). I suspect that experienced birders may pick them up for the first time and not like them because they "don't feel right." Here's my thought: it is worth the 1-2 hours it takes to get used to them, because it will change the way you bird. For example: YOU DO NOT NEED TO CARRY A SCOPE in many circumstances, which is huge. They may be slightly heavy for binos, but they are much lighter than binos plus a scope and tripod!
3) it is easy to underestimate the benefit and power of IS until you have used it for a while in the field. For example, when you are looking for a bird that is mostly hidden in leaves, and occassionally pops into view, these guys are great. The slight vibration in your hand means that you need to see an image longer for the brain to decipher the image. When it is stabilized, you can see it in a flash. You will be able to scan a flock of shorebirds at distance in a fraction of the time it takes someone with a scope. You can see details on a bird moving 100ft above in the canopy that are utterly impossible with normal binoculars.
4) THink of them as ELECTRONICS, not optics. These will not be passed on to your grandchildren. They will last 3-5 years depending on how hard you use them. Don't bother trying to get them fixed because it is uneconomical outside of the warranty period. Don't buy them if you are uncomfortable with the cost because you may need to replace them in the not-to-distant future. That said, reliability has been okay for mine. I have dropped them, gotten them throughly wet for hours, taken them to high altitudes, and exposed them to a wide range of temperatures without any issues. One 12x pair developed a rattle and subsequently a hiccup in the IS. When I openned them up (not recommended) I found that a couple of screws fell out. I don't know where the screws came from and don't really care because now they work fine again.
Here is a comparison of the various models:
12x: the normal "rule of thumb" for birders with conventional binoculars is that 8-10x is about right in terms of image stability, weight, field of view and magnification. With IS binoculars, the equation is a little different. You can have image stability at any magnification, so it comes down to weight, field of view and magnification. For me, the winner is the 12x. You will have a little extra trouble finding a fast-moving bird, especially at close range due to the smaller field of view vs typical 10x. However, it is strong enough to allow me to leave my scope at home for most purposes -- it is equivalent to about a 15-18x conventional scope. The eyepieces are comfortable and the field of view is acceptable. My primary compaint is that the close limit of focus is too far for comfortable use in close quarters like dense rainforest. These binos seem rugged and reliable.
15x: optimal for pelagic birding, gulls and shorebirding, but the field of view and range of focus don't work well for normal birding. On a boat, nobody else will be able to see the stuff you see, period. It is like having a scope when everyone else is using 8x bins. In these circumstances the relatively limited field of view is not an issue and the extra magnification is great. These are much larger and heavier than the 12x and you wouldn't want to carry these on a 10 mile hike (although it would beat hiking 10 miles with a scope!). My main complaint -- and it is a big one -- is that the eyepieces are attrociously uncomfortable for my eyes. Presumably they must be comfortable for someone, like the engineer who designed them, but not for me. I had to replace them with eyepieces of my own because they are intollerable.
10x: These are fantastic. Pros: smaller, lighter than the 12x. Wider field of view and better close focus. Cons: 1) very expensive; 2) eyepieces that are as bad or worse than those on the 15x, which is why I don't own a pair. I think perhaps Cannon made these because they found in their market surveys that birders want 10x binos. I suspect they haven't sold many at the $1,100 price point given the Human factors issues. I personally would advise birds to not buy these unless they are willing to replace the eyepieces -- and better yet just get the 12x. Hopefully the next version will address these issues, because the IS technology and the optics are great.

I have recently purchased the Canon IS 15x50 binoculars for backyard astronomy. I wanted enough "power" to be able to see interesting things without needing to set up a telescope. I researched and read a lot before making the purchase. The binoculars are great! The stabilization makes it possible to get a clear, shake-free view. So far I have been enjoying Jupiter and its moons, double stars, star clusters, and even some Messier objects. As a treat, various meteors flash across, and satellites too faint to see with the naked eye travel by. Even in my light polluted backyard, the binoculars are providing some very satisfying viewing. They are a bit heavier than regular binoculars, but are not uncomfortable, especially if I brace my elbows against my body or the arm of my chair.

I have had these for a few years now, and they still work great. I use them mostly for keeping an eye on the world outside my office window. They are a bit heavy, and they go through batteries fast. Get NiMH AA rechargeables and you'll be glad you did. One oddity - they do not come with objective lens caps, so if you keep them outside their case, it's best to store them standing on the objective end. Luckily they are very stable this way on a table or shelf.
