Option Description
c Single-point AF
User selects focus point using multi selector ( 0 38); camera focuses
on subject in selected focus point only. Use with stationary
subjects.
J
Dynamic-area AF
(9 points)
In AF-A and AF-C focus modes , user selects focus point using multi
selector ( 0 38), but camera will focus based on information from
surrounding focus points if subject briefly leaves selected point.
The number of focus points varies with the mode selected:
• 9-point dynamic-area AF: Choose when there is time to compose the
photograph or when photographing subjects that are moving
predictably (e.g., runners or race cars on a track).
• 21-point dynamic-area AF: Choose when photographing subjects that
are moving unpredictably (e.g., players at a football game).
• 39-point dynamic-area AF: Choose when photographing subjects that
are moving quickly and can not be easily framed in the viewfinder
(e.g., birds).

f 3D-tracking
In AF-A and AF-C focus modes , user selects focus point using multi
selector ( 0 38). If subject moves after camera has focused, camera
uses 3D-tracking to select new focus point and keep focus locked on
original subject while shutter-release button is pressed halfway. Use
to quickly compose pictures with subjects that are moving
erratically from side to side (e.g., tennis players). If subject leaves
viewfinder, remove your finger from shutter-release button and
recompose photograph with subject in selected focus point.
e Auto-area AF Camera automatically detects subject and selects focus point.
