Conclusion: The binoculars are a brilliant piece of optics and technology, second to none. They lack not a thing, are extremely dependable & a sturdy well-built, water-resistant, sealed & coated to perfection. There are no others, on the market, that can stabilize, that are as light and yet durable enough to compare to what Canon has created. They serve for a number of uses, most of which have to do with aviation.
Summary: I had heard about IS binoculars, and although they are expensive, found this set used for the price of a nice regular set. Based on some online research, I first read the instructions (important!) and then put them to work. Blown away. Nothing like I expected. I guess I sort of thought there would be some enhanced digital optimization like a camcorder...not so. Not sure how it works, but impressive. Spoiled me from regular binoculars ever again. Wow.
Conclusion: I'm an observer in a law enforcement helicopter, and we use these binoculars on a daily basis. They are relatively light weight, very durable, and very quick to use. We normally patrol at altitudes of 500 feet, and the power of these binoculars is perfect for the job we perform. The focus is very quick to adjust, and the stabilization button is easily located and operated at the top of the device.
Summary: I needed a second pair of binoculars, primarily for watching football games from row 90 of Michigan Stadium and liked my Canon 10X30 IS so much that I decided to get these. They are really awesome. I feel like I am right in the game. They are easy to adjust, have held up in rainy weather, and produce a crystal clear image. My only complaint is the weight (they seem a bit heavier than the 10X30), but it's worth it.
Pros: Close Focus, Quality Lenses, Strong Construction, Works Well With Glasses
Summary: I purchased these for my husband because he likes to photograph water fowl and he loves the binoculars. Shipping was timely and I am very pleased with the product. Good choice to purchase for yourself or a gift.
