3 Selecting AI Servo AF Characteristics N
Once an AF point starts tracking the 
subject, this setting enables the camera 
to consecutively focus on subjects at 
different distances. If a new subject 
appears in front of the target subject, the 
camera will start focusing on the new 
subject. Also effective when you want to 
always focus on the closest subject.
Geared for tracking moving subjects 
whose speed can change dramatically 
and suddenly.
Effective for subjects having sudden 
movements,...

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.
It is recommended to use this setting 
with the following modes; AF point 
expansion (manual selection  ), AF 
point expansion (manual selection, 
surrounding points), Zone AF (manual 
selection of zone), and 61-point 
automatic selection...

3 Selecting AI Servo AF Characteristics N
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.
It is recommended to use this setting 
with the following modes; AF point 
expansion (manual selection  ), AF

Tracking sensitivity
Sets the subject-tracking sensitivity 
during AI Servo AF when an obstacle 
enters the AF points or when the AF 
points stray from the subject.
0 Default setting. Suitable for moving subjects in general.
Locked on: -2 / Locked on: -1 The camera will try to continue focusing on the subject even if an 
obstacle enters the AF points or if the subject strays from the AF 
points. The -2 setting makes the camera track the target subject...

Acceleration/deceleration tracking
This sets the tracking sensitivity for 
moving subjects whose speed can 
suddenly change dramatically by starting 
or stopping suddenly, etc.
0 Suited for subjects that move at a steady speed (minimal change in 
moving speed).
+2 / +1 Effective for subjects ha ving sudden movements, sudden 
acceleration/deceleration, or sudden stops. Even if the moving 
subject’s speed suddenly changes dramatically, the camera 
continues to...

AF point auto switching
This sets the switching sensitivity of the 
AF points as they track the subject 
moving dramatically up, down, left, or 
right.
This setting takes effect when the AF 
area selection mode is set to AF point 
expansion (manual selection  ), AF 
point expansion (manual selection, 
surrounding points), Zone AF (manual 
selection of zone), or 61-point automatic 
selection AF.
0 Standard setting for gradual AF point switching.

: Equal priority
Equal priority is given to focusing and 
shutter release.
: Release priority

You can set the AF operation charac teristics and shutter-release timing 
during continuous shooting after the  first shot with AI Servo AF.
: Equal priority
Equal priority is given to focusing and 
continuous shooting speed. In low 
light or with low-contrast subjects, 
shooting speed may slow down.
