THE KEY TO USING AND GROUPING AF POINTS

When shooting fast-moving subjects, it can be impossible to keep a single AF point in the right place. To increase your chances of a sharp shot, most cameras allow you to group AF points together to hedge your bets. However, there’s a downside to this, because the more active AF points you use, the more you increase your chances of getting the focus point in the wrong place. If your subject is moving at speed, it is often best to select a small, central group of AF points, as this will offer the best balance between accuracy and utility. But of course, you have to help the AF system by tracking your subject as it moves. So stay on target!
