While attending an astronomy club's night out, one of the members offered to show me a globular cluster using his image stabilized binoculars (brand unknown). As I brought the portion of sky into focus, I pressed the button and -- WOW! I could clearly see the cluster, not because it was highly magnified, but because my eyes had a chance to focus and process the image. Thoroughly impressed, I walked over to my wife and told her of the experience. A few weeks later, we had a pair of 12x36 Canons, and were counting the moons of Jupiter. My wife wanted her own pair so we would not have to readjust them when sharing. She complained about having to hold down the button all the time, something that I don't mind doing as I have long fingers. She also wanted a pair that would focus closer.
SOLUTIONS: We bought her a pair of 10x30's, and to hold the button down, we simply wrapped a strong rubber band, compliments of our postal letter carrier, around them and stuck a short piece of 1/2" dowel rod between the rubber band and the button. The dowel rod is connected to the focus knob by a piece of thread so that, when we do not want the button pushed, the dowel rod does not become lost. We have opted to use lithium cells, rather than alkaline, as they are lighter and last longer, and using our rubber band system will likely mean using the IS much more.
Some reviewers complain that the image still moves as you move. Yes it does, gracefully. What the Canons do well is take out that itty bitty shake that makes things difficult to concentrate on well enough to observe details. Now I can aprreciate eagles as I smoothly track them in flight, or follow the antics of a chipmunk, or count some of Jupiter's 63 moons.
Some complain about the small size of the "exit pupil." Being that my wife and I are in our 60's, a 3mm exit pupil is just about all our eyes can accomodate. They do not seem to be difficult to hold in such a way as to see the whole image. Both of us can leave off our glasses (she is near sighted and I am farsighted), which makes the image even more pristine.
Thanks to one report of the storage case strap breaking, we have opted to use the strap directly connected to the binocs while they are in the case. We simply zip up the case with the straps coming out the top and have had no problem with that system as of yet.
I expect these to require far more protective treatment than our backpacking binocs, and I am quite pleased that they come with a 3-year warranty. I noticed how carefully the astronomy club members treated their equipment and, given how wonderful these Canons are, we will do the same with them. The bottom of their case is padded but, knowing that we will more often than not set them down on that padded end, I have installed a piece of very stiff fiberboard (like the cover of a 3-ring binder) in the bottom of the case to resist anything that might try to poke its way into their objective lenses.
No matter how good the manufacturing, optics are always a compromise and, because of that, someone who does not know any better will always have a critical comment. You simply cannot have it all, at any price. I have been an amateur photographer for over 50 years and consider the optical quality of these to be superb. There is little if any distortion or light loss for nearly 85% of the field of view. Only as the viewed object approaches the last 15% of the field (near the edge) does distortion become noticeable, certainly not objectionable. And why would I focus my eyes on something near the edge when I can move the binocs to bring the object into the center? The nice thing about these, in that regard, is that the distortion is so slight as to not bring attention to itself when viewing a central object.
I should add, at this point, that my first pair of 12x36s did have a defect in the left ocular. Amazon swapped them out so quickly that the binocs practically passed each other in shipping. Good price, good service, and good viewing.
