8. Focus: Your Canon has three main autofocus (AF) modes: One Shot AF for shooting subjects that aren’t moving, AI Servo AF for tracking and shooting moving targets and AI Focus AF, which aims to automatically switch been One Shot and AI Servo if your subjects can’t make up their mind! For photographing birds in flight switch to AI Servo AF to help keep up with the bird. In this mode the AF beep doesn’t sound when you’ve achieved focus, so you need to trust your camera. Use AI Servo with High-speed continuous drive mode and you’ll capture winning shots!
