autofocus lens
Self-adjusting camera glass
A lens with a built-in motor that automatically adjusts focus, eliminating the need for manual focusing.
Most modern cameras use autofocus lenses, which detect subject distance and shift internal elements to achieve sharp focus: The autofocus lens locked onto her face instantly.
Contrast with manual focus lenses, where the photographer turns the focus ring by hand.
