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, Large 
Zone AF, and Automatic selection AF.

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

 Tracking sensitivity
Sets the subject-tracking sensitivity 
during AI Servo AF when an obstacle 
cuts across the AF points or when the 
subject strays from the AF point.
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 cuts across the AF points or  if the subject strays from the AF 
points. The -2 setting makes the camera keep tracking the...

 Acceleration/deceleration tracking
This sets the tracking sensitivity for 
moving subjects whose speed can 
momentarily change dramatically by 
starting or stopping suddenly, etc.
0 Suited for subjects that move at  a steady speed (minor changes in 
moving speed).
-2 / -1 Suited for subjects that move at  a steady speed (minor changes in 
moving speed). It is effective when  0 is set but focus is unstable due 
to the subject’s slight movement or an obstacle...

 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, Large 
Zone AF, or Automatic selection AF.

With AI Servo AF for continuous shooting, you can preset the AF 
operation characteristics and shutte r-release timing for the subsequent 
shots after the first shot  in continuous shooting.

Equal priority is given to focusing and 
continuous shooting speed. In low 
light or with low-contrast subjects, 
continuous shooting speed may slow 
down.
