Selecting an AF point
The AF point is used for focusing. The AF point can be selected auto-
matically by the camera or manually by you. In the Basic Zone modes
and < > mode, the AF point selection is automatic only. In the < >,
< >, < >, and < > modes, the AF point can be selected either
automatically or manually.
The camera selects the AF point automatically according to situation.
You can select any of the seven AF points manually. This is best when you
want to be sure to focus on a particular subject, or to use the time of the
AF function to help you compose a particular shot quickly.
Automatic AF point Selection
Manual AF point Selection
1Press the 
button.()The current AF point will light.
2Select the desired AF point.
•While looking at the AF points on the
LCD panel or in the viewfinder, turn
the < > dial to select the desired
AF point. The selected AF point will
flash in the viewfinder. The AF point
selection will change in the looping
sequence below.
•After selecting the AF point, press
the shutter button halfway. The
camera will then be ready to take
pictures.

Focusing Off-Center Subjects 
If you want to focus an off-center subject not covered by any of the AF
points, use focus lock as described below.
1Select the desired AF point.(→page 32)
2Focus the subject.
•Aim the AF point on the subject, then
press the shutter button halfway.
3Keep pressing the shutter button
halfway and recompose the
picture as desired.
4Take the picture.
Focus lock also works in the Basic Zone modes (except< >). Just start
from step 2above.

When Autofocus Fails 
The camera has a high-precision AF system which can focus almost all
subjects. However, it can fail to achieve focus (the focus confirmation
light < > blinks) the subjects listed below.
Difficult Subjects for Autofocusing•Low-contrast subjects. Example: Blue sky, flat surface with a solid color.
•Subjects in very low light.
•Extremely backlit or reflective subjects. Example: Automobile with a
strong reflection.
•Overlapping near and far objects. Example: Animal behind bars in a
cage.
In such cases, use one of the following methods to focus:
(1) Focus lock an object at the same distance as the subject and
recompose.
(2) Set the lens focus mode switch to  or  and focus manually
as explained below.
If focus cannot be achieved even with the EOS-dedicated Speedlite’s AF-assist
light, select the center AF point.
If you hold down the shutter button halfway while focusing manually, the
active AF point will flash and the focus confirmation light < > will light when
focus is achieved.
Manual Focusing
1Set the lens focus mode switch to
<
MF> (or  on older lenses).The < > icon will be displayed on
the LCD panel.
2Focus the subject.
•Turn the lens manual focusing ring
until the subject is in focus in the
viewfinder.

Selecting the Film Advance Mode
In the One-Shot AF and AI Focus AF (except AI Servo AF) modes (→page
55), when you press the shutter button halfway and focus is achieved, the
exposure is locked automatically at the same time.
The camera has three metering modes: Evaluative, partial, and center-
weighted average metering. Evaluative metering is the standard meter-
ing mode. Partial metering is set automatically when AE lock is used
(
→page 44), and centerweighted average metering is set automatically
in the < > mode (→page 42).
Evaluative meteringThis is an all-around metering mode suited even for backlit subjects. The
viewfinder field is divided into 35 metering zones to which the three AF
points are linked for evaluative metering. The camera determines the main
subject’s size, position, brightness, background, front and back lighting, etc.,
so that it can select the proper exposure for the subject at all times.
Partial meteringThis is particularly effective when the background is much brighter than
the subject due to backlighting, etc. This method uses a center area of
approximately 9.5% of the screen.
• The area covered by partial metering is shown on the left.
Centerweighted average meteringThe metering is weighted at the center and then averaged for the entire
scene.
Two film advance modes are provided: single-frame and continuous shooting.
Press the < > button.
•Show the < > (single) or < >
(continuous) icon on the LCD panel.
Each time you press the < >
button, the icons will appear in the
following looping sequence:
•The continuous shooting speed is
approx. 2.5 frames per sec.

:Program AE 
Like the < > (Full Auto) mode, this
is a general-purpose mode to make
picture-taking easy. It sets the shutter
speed and aperture automatically to
suit the subject’s brightness.
∗“P”stands for Program.
∗“AE”stands for auto exposure.
1Turn the Command Dial to < >.
2Press the shutter button halfway
to focus.
3Check the display.The shutter speed and aperture are
set automatically and displayed in the
viewfinder and on the LCD panel.
•If the shutter speed and aperture do
not blink, a correct exposure will be
obtained.
•If the shutter speed and aperture
blink, see “Exposure Warning List”on
page 53.

The Difference Between < > and < >•The < > and < > modes set the same shutter speed and
aperture settings automatically for picture-taking.
•The following features can be used with < >, but not with < >:
About Program Shift•In the Program AE mode, you can freely change the shutter speed
and aperture combination (program) set by the camera while
retaining the same exposure. This is called program shift.
•To shift the program, press the shutter button halfway and turn the
< > dial until the desired shutter speed or aperture is displayed.
•After the picture is taken with the shifted program, the shifted
program is canceled automatically and the original program is
restored.
•Program shift cannot be set when the built-in flash is used.

:Shutter-Priority AE 
Taken with a fast shutter speed.Taken with a slow shutter speed.
In this mode, you set the shutter speed and the camera sets the aper-
ture automatically to suit the brightness of the scene.
A fast shutter speed can freeze the motion of a fast-moving subject. Or,
a slow shutter speed can blur the subject to give the impression of
motion.
∗“Tv”stands for Time value which is the shutter speed.
1Turn the Command Dial to < >.
2Select the desired shutter speed.
•Look at the LCD panel and turn the
< > dial to set the desired shutter
speed.
3Press the shutter button halfway
to focus the subject.
The aperture is set automatically.

Shutter Speed Display
•The shutter speed can be set and displayed in full and half stops. Shutter
speeds from “”to “”indicate the denominator of the fractional shutter
speed. For example, “”is 1/125 second. For slower shutter speeds, the
numeral is appended with the seconds mark (“”). For example, “”is
0.7 second and “”is 15 seconds.
•When photographing a TV screen, use 1/15 sec. shutter speed for best
results.
•If the maximum aperture (the lowest 
f/number) blinks, it indicates underexpo-
sure. In such a case, turn the < > dial
to set a slower shutter speed until the
aperture display stops blinking.
•If the minimum aperture (the highest 
f/number) blinks, it indicates overexpo-
sure. In such a case, turn the < > dial
to set a faster shutter speed until the
aperture display stops blinking.
4Check the viewfinder display and
take the picture.
•If the aperture display is not blinking,
a correct exposure will be obtained.

:Aperture-Priority AE 
Taken with a large aperture.Taken with a small aperture.
In this mode, you set the aperture and the camera sets the shutter
speed automatically to suit the brightness of the subject.
A large aperture (lower f/number) will blur the background and make the
subject stand out. The larger the aperture, the more blurred the back-
ground will look.
Or, a smaller aperture (higher f/number) will increase the depth of field
to make both the foreground and background look sharp. The smaller
the aperture, the sharper the background will look.
∗“Av”stands for aperture value.
1Turn the Command Dial to < >.
2Select the desired aperture.
•Look at the LCD panel and turn the
< > dial to set the desired
aperture.
3Press the shutter button halfway
to focus the subject.
The shutter speed is set
automatically.
