Camera Technician Question:

Also known as Image Stabilization (IS), Vibration Reduction (VR), or simply image stabilization, anti-shake technology is a method of reducing the effects of camera movement on the photographic image. Image stabilization can be achieved in the lens or in the camera body. In-camera image stabilization is achieved by mounting the camera sensor on a “floating” micro-geared stage that rapidly shifts the sensor in the opposite direction of the camera's movement, which effectively cancels out the image movement. With in-camera image stabilization, the benefits of the system can be realized with any attached lens.
