AI servo mode

For further photography-related information check out my compendium of tips.

Autofocus systems are so sophisticated that they have no trouble locking on to moving subjects, such as Lucy above (click to see her portrait gallery). There's no need to pre-focus on a set point and wait for the subject to run into focus, just set your Canon camera to AI (artificial intelligence) servo mode, lock focus on the subject and then fire away. Combined with the high frame rate of modern cameras this makes it easy to capture sharp action shots.
