Built-in flash and Flash pop-up
button. The flash provides illumina-
tion either as the main light source
or as a fill flash. In Basic Zone
modes such as Full Auto, Portrait,
Landscape, and so on, the flash
fires automatically. In Creative Zone
shooting modes such as P, Tv, Av,
and so on, pressing the Flash pop-
up button raises the flash for use.
✦
Depth of field preview button.
Press this button to stop down, or
adjust, the lens diaphragm to the
current aperture to preview the
depth of field in the viewfinder.
The larger the area of darkness in
the viewfinder, the more extensive
the depth of field will be. At the
lens’s maximum aperture, the
Depth of field preview button can-
not be depressed because the
diaphragm is fully open. The aper-
ture cannot be changed as long as
the Depth of field preview button
is depressed. You can also preview
depth of field when using the Live
View function.
✦
Lens release button. Press and
hold this button to disengage the
lens from the lens mount by turning
the lens to the right to remove it.
Top camera controls
Controls on the top of the camera enable
you to use your thumb and index finger
on your right hand to control common
adjustments quickly. Here is a look at the
top camera controls:
✦
Mode dial. This dial enables you to
switch among shooting modes by
lining up the mode you want with
the white mark beside the dial.
✦
ISO speed button. Press this but-
ton to set the sensor’s ISO setting,
which determines the sensor’s sen-
sitivity to light. In Creative Zone
modes such as P (Program AE
[Auto Exposure]), Tv (Shutter-
priority), Av (Aperture-priority),
and M (Manual), you can select
Auto where the camera automati-
cally sets the ISO from 100 to 800,
or you can set it from 100 to 1600.
In Basic Zone modes such as Full
Auto, Portrait, and Landscape, the
camera automatically sets the ISO
between 100 and 800. Before you
can display the ISO settings screen,
the LCD shooting information dis-
play must be on. If the display is
off, press the Display button to turn
it on.
