Amazon.com Product Description: Canon's 12x36 Image Stabilization II binoculars incorporate an optical image stabilizer for shake-free viewing with minimal eye fatigue. This technology was first developed for Canon video camcorders and is now available in many of Canon's binoculars. The system employs a Vari-Angle Prism, dual transparent plates, independent vertical and horizontal sensors, and a dedicated microprocessor to continuously adjust the prism to maintain a steady image.
These 12x36 Image Stabilization II binoculars feature a water-resistant rubber coating for nonslip holding. If you get caught in light rain, you don't have to worry about the optics fogging up or getting ruined. These binoculars deliver high magnification, long eye relief, and wide-field viewing. Controls for focusing and image stabilization are centrally located and are accessible by both hands.
Improvements to the objective lens assembly have resulted in the binoculars being approximately 26% lighter and 10% smaller than the previous 12x36 IS model they replace. And reductions in power consumption mean a massive 270% increase in battery life of up to four hours using two AA-size alkaline batteries.
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. The binoculars' compact design is based on Canon's popular 10x30 IS model. Curved surfaces mean easy handling, while nature lovers will appreciate the low-reflectance exterior and low gloss front covers, which help to avoid disturbing birds and other
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.
Well worth the money I have used a pair of Cannon 15x50 IS binoculars for about 2-3 years in my job doing environmental field work. Most of the work is performed surveying lake and river shorelines from a 14ft boat with an outboard motor running. We are on the road for about a month and a half during the summer with less intense work in the fall and spring. I have logged hundreds of hours per year with the 15x50 to my eyes. Although they don't smooth out the large jolts of one foot waves or larger at 15-25 mph, it does take out the constant vibration and shake produced from the outboard in the small boat.
We have just purchased the 12x36 IS II for a co-worker as he does more work on land than I and he needed something more portable. He loaned them to me to try out, and they are quite fine . . . much lighter and easier to carry around. The stabilization is as good as the 15x50s. Just hold down the button and the image "floats" rather than shakes all over the place. I haven't tried them long enough to check out the battery life. The specs say they will last twice as long (4 hours) as the 15x50s (2 hours). I go through about two or three sets of batteries per day with the 15x50s so their estimates are probably close as I probably have them engaged 6-8 hours per day. I highly recommend using Eneloop rechargable batteries, and have a set or two charged up for spares if you use the stabilization feature a lot.
The one thing about the 15x50s that is much better is the ability to "lock" the stabilization for 5 minutes (automatically disengages after that time) with a single click of the button (or you can click and hold like the 12x32s). Sometimes in a rough environment, it's tough to keep your finger on the button all the time. With the 12x32s, you must constantly hold the button down when you want stabilization engaged. It's not the most terrible thing in the world, but just not as convenient.
Biggest complaint . . . . where are the lens caps? Even my cheap pair that I use in my kayak have lens caps! But the 15x50s don't come with objective lens caps either. What gives? I am as careful with these as possible, but they are subject to some unforgiving condiions (still haven't dropped them, yet). Lots of rain and rough water but still no problems with the 15x50s. I wouldn't expect less from the 12x32s although they aren't officially rated "All Weather" as are the 15x50s.
Another thing that I noticed is that they don't have a tripod mount. It would stand to reason that you wouldn't need one if you have the stabilization feature, but I could imagine that there would be times where a bird watcher might be set up where a tripod would be adventageous. In my line of work, it doesn't make sense, but it is worth mentioning. The 15x50s are threaded for a mount.
An additional note . . . . a few years ago, I was using my 9x35 Leupolds and saw a plant that I needed to identify on the other side of a shallow weed infested stump field. The plant turned out not to be what I was trying to find, but I still had to shut off the engine, and push and pole the boat through some nasty stuff in hot weather before I could get close enough to make a positive ID. After I got the 15x50s, I was able to view the same plant from open water while my assistant kept driving the boat. I could easily ID the plant without breaking stride. No need to stop or get close. The difference was amazing.
In summary, both the 12x36 and the 15x50 are worth the money in my book, and, if I didn't have the money, I would save my pennies or sell something to get it.
Exceptional optical instrument-a different way of seeing The Canon IS 12x36 binoculars take binocular viewing to a wholly different plane. Image improvement is similar to viewing HDTV vrs old analog TV. The optics of these binoculars are beautiful, multi-coated and distortion free. The instrument fits beautifully in my hands, with weight and balance perfect for observing. The focus knob is deft and sensitive and there is a small notch in the bottom of the barrels where my thumbs fit perfectly. And then, when the IS button is pressed, the image steadies and almost pulls your eyes into the scene. I have used these binoculars at a political rally, where from 100 yards away, I could clearly read the name tags on the chairs of the dignitaries. I have also used them for birding and wildlife. Birds in a distant tree jumped into focus with bright colors and crisp resolution. The same excellent results were seen with wild animals. Truly it is a treat to use this magnificent instrument.
I Can Now See You! Though I gulped at the total price (including shipping) they are so worth it! When I am on the water these make it possible to actually see whales in the distance instead of just fighting the shake/bounce from the boat movement and the waves. The light is excellent and you can roll down the eye cups for glasses. Unless you are really shaky on land, image stabilizers (I don't think) are necessary. But for being able to see when there is a lot of movement this binos are great.
Pricey- and well worth it!!! Simply amazing! Simply stated, these are the best binocs I've ever owned. They are simply amazing in their ability to control the shakes. The optics seem to be of the highest quality with no distortions or imperfections or false colorization. The stabilization technology is amazing! I have a significant "essential tremor" which has limited my ability to use binocs. These binocs "cure" that condition! To see things snap to stable and clear upon the click of a button is a wonder to behold!
Best IS bins for Birders 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.
