Know the Features Image Stabilization (IS)

World Photography - Looks like Image Stabilization feature no longer be foreign to you. Yep, a feature that was first introduced in 1995 by Canon and earned high praise as well as criticism. There is a kind of doubts about this technology, where the technology serves to help reduce or eliminate camera shake from a photograph. This feature was able to prove as a worthy innovation receiving many awards, and it took several years to rivals Canon is able to offer features similar alternative to its customers.

Camera shake occurs usually when you are shooting handheld in low light conditions or when using a long focal length. So it's not unusual anymore when we encounter a telephoto lens is equipped with Image Stabilization feature. Over the years Image Stabilization has accompanied a wide variety of lenses, including wide lens. This feature allows photographers to shoot handheld in low light conditions without worrying about the risk to find the images blur.

Lens with Image Stabilization feature lets you take pictures using a shutter speed that typically cause motion blur. Advantages of Image Stabilization is usually denoted by 'stop'. So the system IS with Three-Stop means you were able to choose a shutter speed as much as Three stops slower than when using a non-IS lens. For example: If you take pictures using a 200mm FL and ideally need at least 1/200s shutter speed to avoid shake, then a lens with a three-stop advantage allows you to use a shutter speed of 1/25 second. Most of today's lens offers superior Three to Four Stops, even some Pro lens that offers up to five Stop.

The manufacturers such as Nikon and Canon have developed these features on their lenses, but there are some manufacturers who install this feature is not on the lens, but on the camera body. Here is the information of different types of stabilizers that exist in every brand:

HOW TO ACTUALLY WORK Image Stabilization?
Actually there are two types of Image Stabilization which is used in DSLR cameras and CSC: One type of features that are on the lens, and the other is on the camera body. Both types of IS are using the principle of a gyroscope to correct for the effects of vibration. the IS in the lens system, there are elements within the lens that is controlled by a microprocessor that uses a gyroscope to detect vertical and horizontal movement. By changing the position of the IS elements of the movement can be compensated to produce blur-free images. IS system built into the camera body has an image sensor that is placed on a platform that can be shifted, and the shift is what is used to compensate for any movement.
