One of the main benefits of the DIGIC Accelerator is a new focusing mode built specifically for photographing sports and action: Action Priority. This intelligent AF mode recognizes specific subjects movements and automatically moves the AF area to the player performing a detected motion, such as taking a shot, making a pass, jumping, and more.
It currently recognizes Soccer, Basketball, and Volleyball activities and can analyze Ball, Joint, Torso, Action, and Head information for tracking. The mode can recognize specific subjects and uses this information in conjunction with recognized movements to determine where to focus in the scene while the action is unfolding.
- Action Priority can be assigned to a custom function button for quick on/off toggling.
- Pre-Registered Person Priority allows you to register up to 10 different people in-camera prior to photographing an event; this information is stored and used to prioritize who to focus on while the game or match is being played.
- Intelligent subject recognition also helps to maintain sharp focus on the intended subject even when it's obscured or crossed by a secondary subject in the frame.
- Can be used in conjunction with Pre-Continuous Shooting mode.
