This section describes the options that control how your camera focuses: fo cus
mode, focus-area selection, and AF-area mode.
Focus Mode
Focus mode is controlled by the focus mode se lec tor
on the front of the camera. There are two autofocus
(AF) modes, in which the cam era focuses automati-
cally when the shutter-re lease button is pressed half-
way, and one manual focus mode, in which focus
must be adjusted man u al ly using the focusing ring
on the lens:
Option Description
S
Sin gle-
servo AF
Camera focuses when shutter-release button is pressed half way. Fo cus
locks when in-focus indicator (
●) appears in view fi nd er, and re mains locked
while shutter-release button is pressed halfway (focus lock). At default set-
tings, shut ter can only be re leased when in-fo cus in di ca tor is dis played (fo-
cus pri or i ty).
C
Con tin u ous-
servo AF
Camera focuses continuously while shutter-release but ton is pressed half-
way. If subject moves, focus will be adjusted to compensate (predictive fo cus
tracking;
52). At default settings, pho to graphs can be taken whether or
not camera is in focus (release priority).
M
Man u al
Camera does not focus automatically; focus must be adjusted manually us-
ing the lens focusing ring. If max i mum aperture of lens is f/5.6 or faster,
view fi nd er fo cus in di ca tor can be used to con fi rm focus (electronic range
fi nd ing), but photographs can be taken at any time, wheth er or not camera
is in focus.
Choose single-servo AF when photographing stationary subjects. Continuous-
servo AF may be a better choice with erratically-moving subjects. Man u al fo cus
is rec om mend ed when the cam era is unable to focus using autofocus.
