Phase Detection Autofocus (PDAF) is a type of autofocus system used in digital cameras, particularly in DSLRs and mirrorless cameras. It works by dividing the image into two or more parts and measuring the phase differences between them to determine the correct focus position. The camera then uses this information to drive the lens’ focusing mechanism, allowing it to quickly and accurately focus on the subject. PDAF is generally faster and more accurate than other types of autofocus systems, especially in low-light conditions, making it a popular choice among professional photographers and enthusiasts.
