AF-Area Mode
AF-area mode de ter mines how the focus area is
selected in autofocus mode. To select the AF-area
mode, rotate the AF-area mode selector. The select-
ed mode is shown by an icon in the control panel
(see below).
Mode Icon Description
Single-area AF
User selects focus area using multi selector; camera focuses on
subject in selected focus area only. Use for relatively static com-
po si tions with sub jects that will stay in selected focus area.
Dynamic-area
AF
User selects focus area manually, but camera uses information
from multiple focus areas to de ter mine focus. If sub ject leaves
selected focus area even briefl y, cam era will focus based on in for -
ma tion from oth er focus areas (focus area selected in view fi nd er
does not change). Use with continuous-servo AF to follow er-
ratically moving subjects and in oth er situations in which it is dif-
fi cult to keep subject in se lect ed focus area.
Group
dynamic- AF
User chooses focus area group (see
right). Camera focuses on center
of selected group; if subject leaves
focus area even briefl y, camera fo-
cuses based on information from
other focus areas in same group.
Use when subject is moving errati-
cally but place of subject in overall
composition is known. Custom

AF, dynamic-area AF, and group dynamic-AF. The illustrations in the “Icon” column show
the display when the center focus area or focus area group is selected. The control panel
display does not show the focus area selected by the camera for dynamic-area AF with
closest subject priority.
