In
AI Servo mode, the Auto Focus (AF) system can keep the auto focus point on a moving target in the frame.

Auto focus cases (presets)
Your EOS 7D Mark II auto focus system comes with six preset cases that you can use.
- Case 1 - Versatile multipurpose
- Case 2 - Continue to track subjects, ignoring obstacles
- Case 3 - Instantly focus on subjects suddenly entering AF points
- Case 4 - For subjects that accelerate or decelerate quickly
- Case 5 - For erratic subjects moving quickly in any direction
- Case 6 - For subjects that change speed and move erratically
Note: Each of these can be further fine-tuned by adjusting the parameters manually (see below).
Understand AF Parameters
The AI Servo mode contains three adjustable parameters that affect how the AF system behaves:
Tracking sensitivity
Determines how quickly the camera will focus on a new subject.
- Locked on - stays focused on moving subject even if the subject moves quickly.
- Responsive - acquires a new subject that enters the frame.
Acceleration / deceleration tracking
Accounts for subjects moving at a constant (0) or erratic pace (setting 1 or 2).
AF point auto-switching
Determines how fast the auto focus points switch from one point to another when tracking a subject.
- Only works with more than one focus point (Zone AF or all 65 AF).
- Setting 1 or 2 may cause the camera to select unwanted auto focus points.
