However, if you have a subject that is continuously moving, you need your camera to readjust focus automatically as you take pictures. If the subject moves, you reacquire focus again and take another picture. When photographing still subjects, you generally acquire focus once and take a picture. When a lens starts to “hunt” for focus, it simply means that a camera cannot find enough contrast and sharpness to be able to acquire focus. If it is blurry, the AF system will adjust the lens focus until sharpness/contrast is achieved. The term “detect contrast” means that the AF system tries to look for sharpness in a particular part of an image. Contrast Detection, It uses the camera sensor itself to detect contrast in the image.Phase Detection, It uses special sensors within the camera to detect contrast from the light that goes through the lens.The Passive AF system works in two different ways: The cons of Active AF is that it can be used only for stationary subjects and it only works for close subjects within 15-20 feet. The pros of active AF is that it can be used in very poorly lit environments, where normal (passive) AF does not function. Once the camera knows what that distance is, it instructs the lens to adjust focus based on this information. The Active AF system works by shooting a red beam on your subject, then bouncing that light back to your camera to figure out the distance between the camera and the subject.
