An Image Stabilizer is a technology used in cameras and lenses to reduce blurriness caused by small movements during shooting. It helps to create clearer images, especially in low-light conditions or when using zoom. This feature is particularly beneficial for handheld photography, where keeping the camera steady can be challenging. There are two main types of image stabilization: optical and digital. Optical Image Stabilization (OIS) involves physical adjustments in the lens or camera sensor, while Digital Image Stabilization (DIS) uses software to correct image blurriness after the photo is taken. Both methods aim to enhance the overall quality of photographs and videos.
