Rating: Summary: Great for learning basic astronomy Review: I bought these binoculars (along with "The Backyard Astronomer's Guide", "Touring the Universe Through Binoculars," and Starry Night software) to learn some basic astronomy. This has turned out to be a winning combination.While these binoculars weigh 2.6 pounds, they have a very natural, comfortable fit in the hands and are easy to handle. The image stabilization is amazing and really improves my ability to resolve stellar objects and surface details of the moon. It does seem a little odd that Canon did not include front lens caps. However the 15x50s are threaded for 58 mm filters, so one can easily purchase standard lens caps. I bought a pair of 58 mm Canon lens caps which fit, although the heavy rubber armor leaves minimal clearance to operate the lens cap release buttons. With filters installed the lens caps fit exactly as they would on a camera lens with plenty of clearance to remove, even if wearing gloves.

Rating: Summary: Outstanding. Amazing. Terrific. Any questions? Review: I've had these binocs (Canon 15x50 IS) for two weeks now and am regretting my purchase . . . . regretting that I didn't buy them years ago, that is!
So far I have put them to work for aircraft spotting, watching hawks soar high overhead, looking at the moon, and general observation of distant terrain. These are by far the best optical instrument I've ever had the pleasure to use. The Image Stabilizer feature is truly outstanding. It allows you to really reach in on astounding views, and enjoy them with rock solid stability.
For example, to focus in on a Boeing 747 that is still 5 miles out on final appoach, and clearly watch it extend its landing gear in all its glory of doors opening, wheels articulating, and doors closing . . . then enjoy watching it float through the air until WHOOOOOOSH it's upon you, is awe-inspiring! And fun!
Another pleasant surprise. The binocs came with two years of extended warranty from Canon free -- three years in total. I wasn't expecting that, but it was in the box when it arrived. Cheers to them!
Prior to buying, I compared the Nikon 14x40 Stabileyes and Canon 15x50 and 18x50 IS binocs and tried them extensively, back to back to back, indoors and out. The Canon's seemed a bit brighter than the Nikon's (as they should be at 15x50 vs. 14x40), sharper, they are more compact although perhaps a bit less robust, and thanks to more heavy discounting and the rebates, they cost about $350 less. The Canons are more highly regarded in the various enthusiast sites as well (both the birders and the astroheads love 'em). The Canon 18's cost $200 more than the 15's, and seemed just a bit "jitteryier" (is that a word?). I am planning to use these for daytime aircraft spotting as well as the night sky, so the 18's just seemed a "bit much" for my needs. The 15's seemed perfect.
Great price from Amazon . . . . $799, before a $100 mail in Canon rebate and a free $50 Amazon gift card. Net cost of $650 is a great deal -- enough so that I justified overnight shipping!
Cheers to Canon for a job well done!
Rating: Summary: Stellar Performance Review: These binoculars are spectacular. Point them at Jupiter and you see a bright dot wandering around in the field of view. Press the image stabilization switch and the planet and its moons instantly become visible. While they can't subtract all movement they do get rid of the little shakes that make hand held viewing so difficult. 15x is enough magnification that Saturn is obviously not round. A complaint about earier versions of the Canon IS line was that your finger went to sleep holding the IS switch down. Now you can press it briefly to turn on the IS circuitry which will automatically shut off in 5 minutes. If you press and hold the switch it shuts off as soon as you release it. I haven't had my pair long enough to comment on battery life but do see a problem changing them when they are mounted on a tripod. Unlike most binoculars where the tripod mounting is at the objective end where the two barrels rotate on the Canons it is at the bottom of the binocular near the center of the tubes which don't rotate. And the battery compartment is just in front of it so you can't get to it if the binoculars are on a tripod of have a quick release plate attached. Since the lens barrels don't rotate intra-ocular distance is adjusted by actually moving the oculars. They are kind of stiff but that is good because they stay in place once you get them set. The tripod mount is lower than the highest part of the lens barrels so if you have a big quick release plate like that of the Manfrotto (Bogen) 410 geared head (highly recommended) it presses against the bottom of the barrels and not the flat between them. For some reason Canon doesn't seem to fell that the objective lenses need any protection as they don't ship lens covers for them. They do provide lens covers for the oculars but they pop off a lot because the eye cups are so soft. It looks like you need something like 69mm lens caps. They don't tell you in the manual but Canon sales says they are threaded to accept 58mm filters so you can buy solar filters for them. I can use the binoculars with my glasses on due to the 15 mm eye relief but it is really easier to use them without the glasses. They are heavy, ~2,5#, but if you support them on the heels of your hands very stable.

Rating: Summary: nothing short of spectacular Review: This is one of the finest optical instruments i ever bought. The Image Stabilizer works so fantastic and flawless you just don't wanna let this bino out of your hand. It even works while you watch from a driving car. You can make out license plate numbers from about 400 ft away. I also bought protective lenses which I use during daytime. When stargazing I realized some mirror effects from the protective lens - so just let those off during nightime. This is the most useful and inexpensive tool for stargazing. Even better than some telescopes for the same price. The AA at 2100 mAh last for about 3-4 hrs. Even with the IS shut off the optics are awesome - but with the IS engaged it is breathtaking. It is definitely worth to spend the extra money to get this system over any other w/o IS.
