Summary: I've used these binoculars for astronomy and bird watching for about 2 weeks. They are outstanding, even without using the image stabilization. It's remarkable to experience how jitter vanishes when the stabilization is engaged: the moons of Jupiter pop out, and central peaks within large lunar craters are easy to see.
Summary: These great binoculars arived just a few days after I ordered them. I've been enjoying them ever since. The image stabilazation is awe inspiring. It cuts down on eye fatigue as well. They are a bit on the heavy side, but thats to be expected. Listed as frequenty bought together are, Canon E-58U 58mm Snap-On Accessory Lens Cap Tiffen 58mm UV Protection Filter I ordered both assuming they were a good idea as there are no lens caps for the large lenses. Neither Item fits.
Birdwatching review -- a better alternative to a scope

Summary: 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.
Summary: I own 9 pairs of Binoculars among them Minolta,Tasco,Olympus that are very nice in there different sizes and I use them for various things,birdwatching/sports/hunting I bought the 15x50s for myself after purchasing the 10x30s for my brother-in-law and seeing how great they worked. The 15x50s are even better than I expected images are crisp and clear even before stabilizing them. I use them for birdwatching right now but will be using them for hunting next fall.
Pros: Quality Lenses, Strong Construction, Works Well With Glasses
Summary: I have recently purchased the Canon IS 15x50 binoculars for backyard astronomy. I wanted enough "power" to be able to see interesting things without needing to set up a telescope. I researched and read a lot before making the purchase. The binoculars are great! The stabilization makes it possible to get a clear, shake-free view. So far I have been enjoying Jupiter and its moons, double stars, star clusters, and even some Messier objects.
Summary: I have had these for a few years now, and they still work great. I use them mostly for keeping an eye on the world outside my office window. They are a bit heavy, and they go through batteries fast. Get NiMH AA rechargeables and you'll be glad you did. One oddity - they do not come with objective lens caps, so if you keep them outside their case, it's best to store them standing on the objective end. Luckily they are very stable this way on a table or shelf.
Summary: My main interest is in astronomy. I have had the Canon 10X30 IS Binocs for awhile and have been very happy. So I decided to take the (substantially more expensive) plunge and get either the 15x50 or 18x50 IS. After reviewing some info on various forums I decided on the 15x50 version. They are outstanding! Sharp, clear optics. Of course the IS sytem works extremely well.
Summary: I purchased these binoculars for my dad for Christmas. I was replacing a garbage pair of 8x36 binoculars that had to be at least 20 years old. Before purchasing, I went to Cabella's to check them out in person. If you're nervous about dropping this much money on binoculars without testing them, head to a local Cabella's store. A note, Cabellas wanted $1299 for these binoculars. I paid $850 on Amazon.
Summary: Canon products are amongst the most innovative I have ever owned. The 15x50 IS Binoculars are no exception. I have used mine for the past five years with much pleasure. My wife uses a Canon 40D camera along with an assortment of Canon lenses (I just got her an EF 70-200mm f/2.8L IS USM for Christmas). We have several 'point and shoot' Powershots floating around.
Summary: These are truly great binoculars and while they are expensive the price was lower than I expected to find. The only complaint is that they don't come with lens covers. You have to buy them separately. For the price Canon should include them.
