Wide Area AF
The Wide-Area focus brackets delineate the focus detecting area in the viewfinder.
Subjects of sufficient brightness and detail can be detected within these brackets. In
addition to general photography, autofocus with Wide-Area focus brackets is suitable for
action photography where the moving subject requires a wide-range focus detection area.
Spot Area AF
Spot Area AF, in which the focus detecting area is designated by the 2.5 mm-diameter
circle at the center of the viewfinder, is recommended when:
✔
The subject is considerably smaller than the wide-area focus brackets*
✔
The subject is obscured by an object, such as a fence, in the foreground.
✔
A particular portion of a subject—such as the eyes—must be in focus in a portrait.
✔
The subject is strongly backlit, such as someone standing beside a bright
window.**
* Lock focus. Refer to “Autofocus with the Main Subject Off-Center” on page 6-36.
** To ensure that the subject is correctly exposed, refer to the “Using the Auto Exposure
Lock Function” section on page 7-4.
