Autofocus
Autofocus is a camera feature that automatically adjusts the lens to focus on a subject. It uses sensors to detect contrast and distance, ensuring that the subject appears sharp and clear in the image. This technology is commonly found in digital cameras, smartphones, and other imaging devices.
There are different types of autofocus systems, including phase detection and contrast detection. Phase detection is faster and often used in DSLRs, while contrast detection is more common in compact cameras and smartphones. Autofocus enhances the photography experience by allowing users to capture moments without manually adjusting the focus.
