Example Concept: In action photography, autofocus systems often use continuous autofocus modes (e.g., AI Servo on Canon, AF-C on Nikon) that track moving subjects and adjust focus dynamically. These systems may also incorporate advanced tracking algorithms and multiple focus points to maintain focus on erratic movements. In contrast, portrait photography typically utilizes single-point autofocus or eye-detection modes to ensure precise focus on the subject's eyes, providing sharp and detailed portraits.
