Selecting AI Servo AF Characteristics (For a Subject)
You can easily fine-tune AI Servo AF to suit a particular subject or scene just by selecting between case 1 to case 6. This feature is called the “AF Configuration Tool.”

About Case 1 to 6
As explained on pages 90 to 92, case 1 to 6 are six setting combinations of subject-tracking sensitivity, acceleration/deceleration tracking, and AF point auto switching. Refer to the table below to select the case applicable to the subject or scene.
Case 1: Versatile multi purpose setting
 | Standard setting suited for any moving subject. Works with many subjects and scenes. Select [Case 2] to [Case 6] in the following cases: when obstacles enter AF points, when the subject tends to stray from AF points, when you want to focus a subject that suddenly appears, or when the subject moves dramatically up, down, left, or right. |
Case 2: Continue to track subject, ignoring possible obstacles
 | The camera will try to continue focusing the subject even if an obstacle enters the AF points or if the subject strays from the AF points. Effective when there may be an obstacle blocking the subject or when you do not want to focus the background. |
If an obstacle gets in the way or if the subject moves away from the AF points for a prolonged period and the default setting is unable to track the target subject, setting [Tracking sensitivity] to [Locked on: -2] may give better results
Case 3: Instantly focus on subjects suddenly entering AF points
 | Once an AF point starts tracking the subject, this setting enables the camera to focus consecutive subjects at different distances. If a new subject appears in front of the target subject, the camera will start focusing the new subject. Also effective when you want to always focus on the closest subject. |
If you want to quickly focus a subject appearing suddenly, setting [Tracking sensitivity] to [+2] may give better results
Case 4: For subjects that accelerate or decelerate quickly
 | Geared for tracking moving subjects whose speed can change dramatically and suddenly. Effective for subjects having sudden movements, sudden acceleration/ deceleration, or sudden stops |
- If the moving subject suddenly and greatly changes speed, setting [tracking] to [+2] may give better results
Case 5: For erratic subjects moving quickly in any direction
 | Even if the target subject moves dramatically up, down, left, or right, the AF point will switch automatically to focus-track the subject. Effective for shooting subjects that move dramatically up, down, left, or right. This setting takes effect when the following AF area selection modes are set: AF point expansion (Manual selection  ), AF point expansion (Manual selection, surrounding points), Zone AF (Manual selection), 61-point automatic selection AF. This setting is not available with the Single-point Spot AF (Manual selection) and Single-point AF (Manual selection) modes. |
If the subject moves erratically up, down, left, or right, setting [AF pt auto switching] to [+2] may give better results
Case 6: For subjects that change speed and move erratically
 | Geared for tracking moving subjects whose speed can change dramatically and suddenly. Also, if the target subject moves dramatically up, down, left or right and it is difficult to focus, the AF point switches automatically to track the subject. This setting takes effect when the following AF area selection modes are set: AF point expansion (Manual selection ), AF point expansion (Manual selection, surrounding points), Zone AF (Manual selection), 61-point automatic selection AF. This setting is not available with the Single-point Spot AF (Manual selection) and Single-point AF (Manual selection) modes. |
- If the moving subject suddenly and greatly changes speed, setting [tracking] to [+2] may give better results
If the subject moves erratically up, down, left, or right, setting [AF pt auto switching] to [+2] may give better results
