Camera shake is a common problem in photography, especially when using a telephoto lens. Telephoto lenses magnify the image, which also magnifies any camera shake. This can result in blurry photos. Image stabilization is a feature that helps to reduce camera shake and produce sharper photos. There are two main types of image stabilization: optical image stabilization (OIS) and electronic image stabilization (EIS).
OIS uses a movable lens element to compensate for camera shake. This type of image stabilization is usually found in higher-end cameras and lenses. EIS uses software to compensate for camera shake. This type of image stabilization is usually found in less expensive cameras and lenses.
Both OIS and EIS can be effective at reducing camera shake and producing sharper photos. However, OIS is generally considered to be more effective than EIS. This is because OIS compensates for camera shake before the image is captured, while EIS compensates for camera shake after the image has been captured. This can result in sharper photos with OIS.
