autofocus
Autofocus is a feature in cameras and optical devices that automatically adjusts the lens to make a subject appear sharp and clear in an image. It uses sensors to detect the distance to the subject and communicates with the lens to achieve the correct focus. There are different types of autofocus systems, such as phase detection and contrast detection, each with its own strengths. This technology allows photographers and users to capture sharp images quickly and easily, without manually adjusting the focus. It’s especially useful in fast-paced situations or for capturing moving subjects.
