AF Mode and Focus Area

Your camera features two Autofocus modes, Single Servo AF (AF-S) and Continuous
Servo AF (AF-C). The autofocus system offers a choice of two focus areas, Wide (

)

and Spot (

). AF mode and focus area are set simultaneously. Refer to “Setting AF

Mode and Focus Area” on page 6-32.

AF-S Single Servo AF

Lightly pressing the Shutter Release button activates the lens focus adjustment. Because
the priority is on correct focus, the shutter will lock until a stationary subject is in focus
(showing in the viewfinder) or until the camera anticipates a moving subject to be in
focus. After focus is achieved with a stationary subject, the focus remains locked for as
long as the Shutter Release button is lightly pressed. This feature proves especially useful
when recomposing a picture with the main subject off-center (page 6-36). If the camera-
to-subject distance changes, however, you must refocus.

AF-C Continuous Servo AF

Under certain conditions, such as very fast action situations, you may want to capture an
image even before focus is successfully achieved. In such cases, use Continuous Servo
AF. As you lightly press the Shutter Release button, focus detection begins and the lens
continues focusing for as long as you keep the button lightly pressed. Since the priority is
on shutter release, you can capture an image regardless of focus status.
