When you think about binoculars the quality of the optics is always paramount, however regardless of the optical quality if you can’t hold the binocular steady the image quality will suffer. Canon have designed a range of binoculars which combines quality optics with hi-tech electronics allowing previously unusable magnifications to be hand held.

So whether you’re after high magnifications without the need of a tripod or if your hands aren’t as steady as they used to be take a look at the Canon IS range & there will be a model to suit your needs.

Just 12 cm wide and weighing only 490g. the new 8x25 IS binoculars are the most compact and lightweight IS binoculars Canon has ever developed.

The new IS binoculars have an appealing rounded shaped design for more comfortable handling. They owe their small size, low weight and superb image-stabilising ability to the latest in Image Stabilisation technology: the Tilt Mechanism. This mechanism keeps your subject steady by correcting movements, such as hand shake. Battery power is minimised because the IS optics only uses power when the IS button is pressed. Like the focusing knob, this button is centrally located on the binoculars, easily reachable by both left and right handed users. As a further refinement, the tilt-system Image Stabiliser of the 8x25 IS suppresses chromatic aberrations and reduces colour 'smearing' in order to keep your image clear. Being environmentally conscious Canon have used lead-free glass in the new IS binoculars.

Almost everybody who has ever used binoculars at sporting events or concerts has experienced how much the images shake, and you feel that the binoculars are useless. The main complaint of users has been image shake. The higher the magnification, the larger the image shake. In general, any binoculars with over 10x magnification should not be used for a long time. The best solution in the past was to use a tripod. However, tripods are bulky and can't be used everywhere. Even if you need a pair of binoculars of over 10x magnification for bird watching, the most you would want to use since you walk around a lot would be something of 7x or 8x magnification.

Canon is the worlds first maker to use an active optical image stabilizer for IS series. Because two Vari-Angle Prisms are controlled by a microprocessor, hand shake is eliminated. As a result, even with over 10x magnification, a tripod is not needed. And they can even be used while viewing from a moving car or train! In addition to the light weight, there is no eye strain to make you tired, so it is possible to use these binoculars for a long time.

The image quality around the edges is a very important point to look at when selecting binoculars. If binoculars with inferior image quality are used for an extended period of time, the user will tire easily and may even become sick. The IS series use the worlds first doublet field-flattener lens. This is Canons exclusive optical design with two field-flattener lenses, lenses which are normally reserved for high-grade binoculars. By using two lenses, Canon has achieved a wide field of view of 67° (12x36 IS, 15x50 IS ALL WEATHER, 18x50 IS ALL WEATHER), with unrivaled sharpness.

The bird that you were following from afar suddenly came close to you. One problem you encounter is the closest focusing distance. In general, the more magnification the binoculars have, the longer the focusing distance. There are plenty of times when you had no choice but to watch with the naked eye, because you couldn't focus in time. Also, when you are bird watching, you are constantly walking around with a pair of binoculars. For that reason, you would like to carry around something light.
