Dual Pixel autofocus is a technology used in digital cameras that enhances focusing speed and accuracy. It works by using two photodiodes for each pixel on the image sensor, allowing the camera to quickly determine the distance to the subject. This results in faster and more precise autofocus, especially in challenging lighting conditions. This system is particularly beneficial for capturing moving subjects, making it popular in DSLR and mirrorless cameras. By providing continuous focus during video recording and fast shooting, Dual Pixel autofocus improves the overall photography experience for both amateurs and professionals.
