Focusing options to suit your shooting style
New AF/MF button for easy focus mode
switching
The key to easy, responsive focusing is the ability to
switch seamlessly between auto
(
AF
)
and manual
(
MF
)
operation. On the
, a focus drive clutch
mechanism enables you to switch back and forth be-
tween the two simply by pressing the new AF/MF but-
ton on the back of the camera. Operation is so intui-
tive, there's no need to alter your grip or take your eye
from the viewfinder. A dial on the front of the camera
provides easy access to four focusing modes: manual
focus
(
MF
)
, single AF
(
AF-S
)
, continuous AF
(
AF-C
)
, and
an auto AF
(
AF-A
)
mode that automatically switches
from single AF to continuous AF when the system de-
tects that a subject is moving. By combining AF/MF
button switching with the high-speed, high-precision
AF mode of your choice, you can enjoy accurate and
responsive focusing in virtually any situation.
The AF illuminator on the front of
the camera has a range of up
to 7 meters, and automatically
provides supplementary illumi-
nation to enable accurate
autofocusing even in the dark.

4 Focus Modes
S: Single AF
A: Auto AF
C: Continuous AF
M: Manual focus
When the AF/MF button is pressed, it switches focus modes by
toggling the position of the focus clutch. The button can be cus-
tomized to switch focus modes each time the button is pressed,
or to switch modes only while the button is pressed.
Bright, clear viewfinder for easy focusing
The bright, clear viewfinder features a precision-
ground optical glass pentaprism and a high refractive
index eyepiece lens, treated with an anti-reflective
coating to help prevent ghosting. A spherical acute
matte focusing screen aids manual focusing by mak-
ing it easy to identify the correct focus point.

AF activation
Although autofocusing is ordinarily activated by press-
ing the shutter button half-way, the Sony Eye-Start sys-
tem automatically activates it for you as soon as you
grip the camera and put your eye to the viewfinder.
And that means you’re ready to start shooting sooner,
and are able to make the most of almost every photo
opportunity.
