In these situations, Case 4 is most effective. With the 
[Accel./decel. tracking] parameter set to [+1], the AI 
Servo AF will work to focus track any changes in speed, 
including sudden stops and acceleration.
This makes Case 4 the most effective setting for shooting 
soccer, rugby, basketball or sports where there is a lot of 
running and stopping, as well as changes of direction 
which was difficult for Case 1 to track. It is also effective 
for cornering during motor sports (sudden deceleration 
and acceleration), and starting dashes.

Case 4
For example, the start of a track and field event. With 
Case 4, the movement of the runner is captured in the 
moment from the resting state to sudden acceleration. 
By using Case 4 the AF system reacts to sudden changes 
in speed, allowing accurate focusing of the starting dash 
moment.
