Action photos require your EOS camera to track a subject and continually update focus until the photo is captured. Selecting Servo AF is only the most basic step to make this happen. Many cameras have a range of additional settings to refine how a camera autofocus responds to different subject dynamics. Almost regardless of the actual subject speed, it’s how it moves that determines how AF needs to respond; a fast car on a race track moving towards or away from the camera is consistent and quite easy for the camera to predict where it will be when the photo is taken. A small bird in flight changes direction much more rapidly and so benefits from different focus settings to maximize the chance of each shot being sharp.
Most EOS R System cameras have a range of subjects that can be detected to aid positioning of the AF point, but it doesn’t change how the camera focuses. This is why AF cases are important. Mirrorless cameras have four preconfigured AF cases, plus an auto case that profiles the subject movement and selects suitable settings automatically. Auto is suitable for all general photography, but there are situations requiring a specific response.
