The 18x50 Image Stabilized binoculars feature a shock-resistant, water resistant rubber coating for a nonslip grip, better durability, good handling, and for protection against rain & splashing water. You don't have to worry about the optics misting up if you get caught in the rain and still need to view. These binoculars render high-magnification and wide-field viewing. Controls for focusing and image stabilization are centrally placed and accessible by both hands. These binoculars provide long eye relief for added comfort and allows the use of eyeglasses without vignetting of the image.
What is an Image Stabilizer?
The more powerful the binoculars, the more shakings are magnified. As a result, even a little sway of your hands will shake the image in the binoculars a great deal. Usually, we can bear this image shake with binoculars up to 7x magnification. The image shake would quickly get unbearable With higher-magnification binoculars.
However, with Canon's Image Stabilizer turned on, the image shake becomes tolerable even at magnifications of 15x and 18x. Such high magnifications were previously unthinkable in a pair of binoculars without the use of a tripod. TheImage Stabilizer steadies the image instantly and brings out the top-notch optical performance of the lenses.
Image Stabilization and More
Canon's IS technology is outstandingly good at eliminating the sway problem and is widely applied by the television industry with Canon's professional broadcast quality video recording equipment. An exceptional VAP (Vari-Angle Prism) corrective IS system sits within the objective lens group and the porro prism on each side of the binoculars. Within one-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 modifies to refract or 'bend' the light path by exactly the right amount, thus fully compensating for the vibration.
Super Spectra Coating
A number of optical elements affect the brightness of an image, including the total of incidental light that is reflected by the lens. An uncoated lens will reflect away as much as 8% of the incidental light, significantly dimming the image. Canon's Super Spectra Coating prevents that reflection.
What do the numbers mean?
8x25? 15x50? 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 in the objective lens. To illustrate, if you use a 10x lens and view at an object that is 200 yards away, it looks to be the same size as an object placed just 20 yards away. The second number, the size of the objective lens, is crucial because the larger the objective lens, the more light it can accept for brighter, more detailed images, and the better suited they will be for low light situations.
