Expanded Definition

Focus tracking is a feature of some cameras that allows the camera to keep a moving subject in focus. This is especially useful when taking pictures of fast-moving subjects, such as sports or wildlife. To use focus tracking, the photographer first needs to select the subject that they want to keep in focus. The camera will then track the subject and adjust the focus accordingly. Focus tracking is a valuable tool for photographers who want to make sure that their photos are sharp and well-composed.
