Camera Glossary

Technology that reduces blur from camera shake, either through lens or sensor movement.

Detailed Explanation

Image stabilization (IS), also known as Vibration Reduction (VR) or Optical Stabilization (OS), is a technology that compensates for camera movement during exposure. It can be implemented in-lens or in-camera through sensor movement. This feature is particularly valuable in low-light conditions or when using telephoto lenses, allowing photographers to shoot at slower shutter speeds while maintaining sharpness. Modern systems can provide 5-8 stops of stabilization, significantly expanding handheld shooting capabilities.
