What is Autofocus Type?
Describes the technology a webcam uses to automatically adjust focus for clear images.
Definition
Autofocus type specifies the underlying mechanism a webcam employs to achieve sharp focus on subjects. Common types include Phase Detection Autofocus (PDAF), which uses phase differences to quickly determine focus distance, and Contrast-Detection Autofocus (AF), which finds focus by maximizing image contrast.
Why It Matters
A good autofocus type ensures you remain sharp and clear during video calls, even if you move, preventing blurry or out-of-focus footage.
What to Look For
PDAF generally offers faster and more accurate focusing than standard contrast-detection AF, especially for moving subjects.
