They are, and they aren't, great binocspWhat 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.pWhat 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.

I bought these binoculars because I was just a bit frustrated with using regular binoculars. I already have a set of weatherproof Minolta binocs that cost about $200, but wasn't finding it useful because the effort required to hold it steady enough to see detail just made it fatiguing to use for any length of time
br /
br /Seeing as I've had great success with Image Stabilization in SLR lens, and my point and shoot, I thought I would give this Canon a try
br /
br /I like it. It's quite light for its size, and compact enough that I don't feel burdened to bring this with me for any kind of event short of a long hike up a large mountain. It does take a CR123 battery which is kind of expensive if you buy them at a department store. You should try to find them online. Many high end flashlights use this type of battery, and they are available for around $2 online. Surefire (a top flashlight brand) batteries are what I recommend and use everywhere (in my flashlights and cameras). These kinds of batteries have a long shelf life so it's no problem to buy a few extra
br /
br /The main reason for this binocular is the stabilization. In reality, the Image Stabilization is actually quite subtle. You still have to do your best still to keep the binocs steady, but the stabilization adds a just bit extra steadiness to the image, enough to make a difference you can notice. You have to keep the button at the top of the device pressed with your finger...it turns off as soon as you let go of the button.
br /All in all, the IS works well for the natural minute shakiness of your hand but larger movements are not compensated for as you would expect. So don't expect the image to be steady if you are trying to spot animals from inside a car. If you deliberately move the binoculars side to side, you can see the mechanism doing its work as it floats and then hits its limits.
br /
br /The drawbacks...
br /
br /- the eye relief is only 13.5 mm...so it's not really suitable for eyeglass wearers. I find an eye relief of 16mm minimum to be very usable with eyeglasses.
br /- uses harder to find CR123A batteries.
br /- the device isn't water resistant, so you have to keep this thing completely dry
br /- Image Stabilization effect is quite bit more sutble than you might expect, but it's definitely effective enough to be noticeably more steady than a normal binocular
br /
br /I think the future of binoculars is definitely IS. I see that Canon has a version 2 of their IS in a more expensive model, so maybe the action of the IS is improved and may be added to this model in the future. If you are a casual user who just wants an effective binocular, this is a great one to choose. Canon makes higher grades and higher magnifications for the more serious user.

I have to give these binoculars 5 stars, not because they are the finest optics money can buy, but because they give the clearest and steadiest handheld viewing you can get at anywhere near this price. Value for the money is the point, here. But, besides value, they actually are very good quality optics! They feel well made. Although they are mostly plastic, it's good quality material, they don't feel cheesy. No, they are not built like a Leica tank (intended to survive an atomic blast), but the image stabilization is so amazing, I am willing to be a little extra careful with them. You look through them and press that button, and, PRESTO, the view just stops jiggling! It's just fantastic! The I.S. has greatly improved my stargazing pleasure. Maybe I have especially bad hand tremor, but I would bet anybody would notice a big difference. I really love them!!

I used these binocs extensively for several days on African safari to view animals and birds. The night skies were clear so I tried it on a few astronomical objects. As an experienced telescope user I can say the optics are a bit disappointing. There is noticeable chromatic and other aberrations. Of course, an astronomical test is pretty severe compared to a landscape type of view. In daytime viewing most people probably wouldn't notice the deficiencies. Focusing is easy.
br /
br /The image stabilizing feature is amazingly effective. After initially being a bit underwhelmed, I can say the IS technology makes these binocs hugely more useful than an improvement in the optics would. For stationary or moving objects, it works to near perfection. I used my left hand to focus, right hand to hold the IS button, and both functions were comfortably reachable.
br /
br /Other good facts--the battery life seems very long. Not sure exactly how many hours but I'm on the first battery still and it's been several months of intermittent (and more recently, heavy) usage.
br /
br /And they really are lightweight. That makes them superior to larger, better, heavier binocs that you don't use as often because they're not as convenient. You will take these around with you frequently.
br /
br /Eye relief is fine. For eyeglass wearers, you can fold back the rubber eyecups and put the lens right up to touching your glasses, and you can get a full field of view.
br /
br /And at around $240, excellent value.

I just received my Canon 8x25 IS binoculars and they are just as sharp, bright and contrasty as my Pentax DCF WP 8x42 binoculars but show more detail when using image stabilization. They weigh only 16 oz so they are perfect for hanging from your neck for extended birding, sightseeing etc. You will not find better optics in their price range that includes a $50 Canon rebate until July 15. I also have the Canon 10x42L IS WP and 12x36 IS II binoculars but they are much larger and can get heavy when hanging from your neck for extended periods.

I couldn't help myself buying these after reading the reviews (all magnifications). I got it for $170 A/R.
br /
br /When I took it out case and look through, I was a little bit dissapointed. The IS effect was not so obvious. But after a while I got used to it. I think it is not bad.
br /
br /The binoculars are nice themselves without IS. The IS effect is not so big becasue I think this is only 8 times magnification.
br /This is the only reason that I am giving it a 4 star ranking instead of 5.
br /
br /But don't get me wrong, the IS effect is there. I can read smaller words with IS on. So I suggest buying higher powers if you can afford them and you are OK with their sizes and weights. The higher power the better IS effet.
br /
br /Now about those whines,
br /1. Battery.
br /It is said one cr123a can be used for 6 hours. It is OK and it's not expensive if you buy them online ($1.5 each).
br /
br /2. Object lens caps.
br /I put eye lens caps on object lens, they fit well.
br /
br /3. Durability.
br /It's a fine product. What do you wanna do with a fine optical product other than using it with care?

My husband and I love these binoculars. I was concerned about paying extra for the image stabilization and I really don't understand how it works, but I think it's great. You really pick up detail that you would otherwise miss due to you hands shaking. I would highly recommend these binoculars.

Image stabilization (IS) is well worth the modest incremental cost and bulk of binocs w/o IS. You can see detail better and not get headaches from jitter. Almost as good as putting non-IS binocs on a tripod. I'd give it 5 stars if I didn't have to constantly hold down the image stabilization button. I'm sure Canon did that to prevent running down the batteries. However, it would have been nice to push once and have IS stay on for 30 seconds or so.

The image quality is excellent. Eye relief is good so these binoculars are easy to use. The image stabilization is amazing. I use them for star gazing and would not go back to binoculars that are not image stabilized. The improvement in seeing is amazing when the IS is engaged. I also use them for concerts etc. and IS makes all the difference.
br /Battery life has been good using the IS function 99% of the time. Since I am a casual user two batteries last about a year.
br /
br /I would have liked to see a push on push off type of switch for the IS instead of having to push and hold the IS switch to keep it engaged.
br /
br /Focusing is relatively easy even while holding down the IS button, which is located on the top front by the way.
br /
br /After using 8x25 and experiencing IS for the first time I wish that I would have gotten the next higher magnification because it works so well.

I have taken this binocular on several vacations. It is a neat binocular. The image stabilization worked great. It is not a gyro stablized binocular, so don't expect it to be a still image. I was on a police helicopter one time and they had the gyro stablized binos that were amazing. While hovering 1000 feet away, you can see everything clearly while the helicopter is in motion. Don't expect that with this bino. You are not paying thousands of dollars for it either. For the amount of money, this bino was a good deal. First the size is perfect. It is not small, but it is not big either. It was comfortable to have hanging around your neck. It wasn't too heavy. The images were clear and when you press the button, the image stablization kicks in. When you release the button, the IS stays on for a few more seconds, so you don't have to press the button constantly. The only thing I wish is that they would add an extra set of lense covers. You can use them to cover the view holes as well as the front lenses. The battery lasted a long time as matter of fact, I'm still on my first set and I've had it for several months now and have taken it on numerous vacations.

It is funny to see one reviewer compare it to the 8X32 Leica. because I am about to do the same thing. I just happen to own a Leica 8X32 also. Actually I agree 100% with the comparison from other reviewer. The IS function works so well that the Canon 8X25 IS and Leica 8X32 are comparable on hand held application, except the Canon is slightly dimmer than the Leica. There is no doubt that Leica will beat the Canon on a tripod, due to the better optic of the Leica.. For 5X the price it should. Also for 5X the price it also buy you the water proof and rubber armor. The Leica is more than twice as heavy as the Canon. You might call that Canon has the upper hand on Leica.
br /As for reliability, that is a different story. My Leica 8X32 has served me more than 15 years and still good as new. The IS function of the Canon 8X25 ISfailed after 15 months. Fortunately for the reason we can guest, this is the only product that Canon carries a 3 year warranty ( even the DSLRs from Canon carries only 1 year warranty). However it take at least 4 phone calls from me and from Canon USA to convince the repair department to fix it under warranty instead of charging me $450 to fix a $175 binocular.
br /A friendly advice: make sure that it comes with a 3 year warranty before you buy it. Or you can pay extra to buy the extended warranty.

I purchased these binoculars for use on a 30 foot fishing boat. They work great. The image is clear and when I activate the stabilization, I can read caution and slow notice signs from a long way off. I know that some reviewers have concerns about them not being waterproof. As long as you don't drop them in the water, they seem fine.

The stabilizer feature is a real plus. Fits very well in my small hands

I've returned from a River Barge Excursion (8 days on the Ohio Mississippi Rivers), and I used my Canon IS binoculars ALL the time. I purchased additional 123 Photo batteries, anticipating I would 'use up' the original battery from constant use, but so far haven't made a battery change.
br /
br /I did manage to lose one of the eyepiece caps, and I plan to contact Canon to see if I can purchase a set of replacement caps. I also have / use a Canon Powershot S5 IS digital camera, and the lens cap is tethered to the neckstrap, which is a very convenient place to 'put' the lens cap while using the camera. I would like to see Canon design a similar 'tethering' for their binocular eyepiece caps.

Fabulous pair of binoculars for the price. Image quality is crystal clear
