Standard setting suited for any moving 
subject. Works with many subjects and 
scenes.
Select [Case 2 ] to [Case 6 ] in the

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 su bject, the camera will 
start focusing the new subject. Also 
effective when you want to always focus 
on the closest subject.
Geared for tracking moving subjects 
prone to sudden, dramatic changes in 
speed.
Effective for subjects with sudden

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

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] Standard setting suited for most moving subjects.
[Locked on: -2 / Locked on: -1 ]
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. The -2 setting makes the ca mera track the target...

 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 fixed speed.

Effective for subjects having sudden movements, sudden 
acceleration/deceleration, or sudden stops. Even if the moving 
subject’s speed suddenly changes  dramatically, the camera
