Phase Detection Autofocus
An instantaneous autofocus system comparing incoming light wave phases to determine both distance and direction of necessary focus movement.
Detailed Analysis & Visual Theory
Phase Detection Autofocus (PDAF) represents an essential cornerstone of photographic expression, visual narrative, and technical mastery.
