can be difficult for the AF system to judge

accurately, In these situations, Case 4 is most

effective. With the [Accelerate / decelerate

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. It is also effective

for cornering during motor sports (sudden

deceleration and acceleration).
