As an experienced brider (bird watcher to some) I've owned some of the world's greastest optics, the type of European "alpha-glass" that top tour leaders wear with pride.I bought the Canon 12x36 almost 2 years ago based mostly on my respect for the Canon L lenses with internal stabilization that I use on a regular basis for bird photography.All I can say is... Wow!.These light-weight, high powered lenses have become my favorites in the field for wildlife observation, especially when viewing wild birds.
At first they took a little time to get used to.They really don't have the feel of a top-of-the-line pair of binos (they are somewhat darker than most and setting the eye-peices for your own interocular distance is a little strange compared to the roof prism glasses that many of us have become accustomed to), but they are what they are.These are not your daddy's binoculars.However, if you are looking for state-of-the-art high tech optics, look no further.
When a subject is focused you see the type of image shake that one would expect at 12x magnification.Then I depress that wonderful little button that activates the image stabilization feature. All of a sudden I feel as though I am now looking at the bird face to face, like I'm just THREE FEET AWAY!It's as if I was studying the bird in a book.I can see details and field marks that others only wish that they could.It has helped me to make some really tough indentifications for my life-list that I might not have recorded otherwise.
After being so pleased with the 12x I decided to buy the 18x50's.I've owned them both now for a while and I find that I take the 12x36's out much more often that the larger, heavier 18x. I highly recommend the Canon 12x36 for serious nature (and or sports) observation.

Product Description:
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.
