What is "autofocus"?
Autofocus is a camera feature that automatically adjusts the lens to achieve a sharp and clear image of a subject. It uses sensors and algorithms to detect the subject’s distance and determine the correct focus distance. Autofocus helps photographers quickly and accurately focus on moving or stationary subjects without manually adjusting the lens. There are different types of autofocus systems, such as phase detection and contrast detection, each with its own method for achieving precise focus.
