 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 a case from 1 to 6. This feature is called the “AF Configuration Tool”.

> dial to select a case icon, then press <>.

  • The selected case will be set. The selected case is indicated in blue.

    About Cases 1 to 6

    As explained, cases 1 to 6 are six combinations of subject-tracking sensitivity, acceleration/deceleration tracking, and AF point auto switching settings. Refer to the table below to select the case applicable to the subject or scene.

    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 subjects, 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 focus on the target subject is lost with the default setting, 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 prone to sudden, dramatic changes in speed.

    Effective for subjects with sudden movements, sudden acceleration/ deceleration, or sudden stops.

    If the subject is in motion, and prone to sudden, dramatic changes in 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 is prone to sudden, erratic movements 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.
