Advanced site description
Even in photographs taken by most high-quality mirror camera, periodically there are "ghosts" - the blurred shapes, objects and persons, who sometimes spoil the frame so that it can only be deleted. Manufacturers phototechnics long struggled with this disease for quite some time, developing a variety of image stabilization system which certainly helps, but again, not always, because they can not repay all the vibration. Cardinal solution to this problem suggested the company Canon.
The latest optical image stabilization system Hybrid IS (Hybrid Image Stabilizer) is created in such a way that will put out not one but two types of vibrations that will make the picture even more clear. According to the representatives of the company, the system still has no analogues, and this jerk in the future will benefit from Canon cameras to rebuild their direct competitors.
Not one person in the world can not hold the camera in the hands of perfectly flat. For those of a second, which pass from the moment you press the button and before the camera work, the human hand must have time to flinch. A clear, sunny day, or when using flash is usually not important, the pictures still come out quite clear. But in low light, or, say, when shooting with shutter priority, which gives the images a particular depth, the slightest tremor causes the future of photo-masterpiece of irreparable harm. Usually, for secure fixation camera, basically, use a tripod, but it's not always convenient, and indeed may, therefore, manufacturers of cameras, and, in particular, Canon, have been fighting for image stabilization.
There are two basic types of camera shake when shooting hand. First, the "walk" up and down the lens, and secondly, moves in space the whole entire camera. Existing date image stabilization system can pay off only one of them, while specialists Canon taken to cope with both at once.
Canon has gone a long and thorny path in the development of image stabilization. The first study began in 80s, but only in 1995 saw the light EF 75-300mm f/4-5.6 IS USM, the world's first removable lens with a mechanism to compensate for camera shake. Of course, experts Canon does not rest on its laurels and has since made a number of modifications like interchangeable lenses. Now in the line of manufactured products have 21 lens with such properties.
New, hybrid technology compensates for a Canon camera movement in space, and change the angle of the direction of the lens. The latter problem is often interferes with normal photography, at the time, as the first most strongly influences the image quality and macro shooting from close range.
New technology includes an angular velocity sensor, which determines the angle of the lens camera shake and was present in all previous optical image stabilizer Canon. In addition, it also includes a new acceleration sensor, which determines the strength of shaking produced when moving the camera. Also in the new system of Hybrid IS present a new algorithm that synthesizes information from two sensors for optimal adjustment of the image. This system clearly enhances the effect of stabilization not only during normal, but during the macro, which until now has been too tough for cameras with image stabilization.
Canon plans to use new technology in a large number of new products. According to company announcements, lenses, equipped with the new system are likely to go on sale before the end of 2009.
