Shutter-priority AE [Tv]
Shutter Speed Display
Shutter speeds are set in 1/3-stop increments. From 8000 to 4, the shutt\
er speeds are dis-
played as the reciprocal of the actual time values. For example, 125 on \
the display indi-
cates a shutter speed of 1/125 sec. For shutter speeds slower than 4, ac\
tual times are dis-
played. For example, 0”3 on the display indicates a shutter speed of \
0.3 sec, and 15” indi-
cates a speed of 15 sec. The following shutter speeds are available:
8000   6400   5000   4000   3200   2500   2000   1600   1250   1000   80\

2. Aperture-priority AE [Av]
In this mode, you set the aperture and the camera automatically sets the\
shutter speed according to the lighting conditions.   
1While pressing the shooting mode
selector, turn the main dial until “Av”
appears in the LCD panel.
2Release the shooting mode selec-
tor.
3Turn the main dial until the desired
aperture value appears in the
viewfinder or LCD panel.
4Press the shutter button halfway to
focus the subject and confirm the
exposure.
• The aperture value and corresponding
shutter speed are displayed in the
viewfinder and LCD panel.

							•When a shutter speed of 30” blinks in the display, the image will be \
underexposed.
Turn the main dial to set a larger aperture (smaller aperture number) \
so the shutter
speed stops blinking.
• When a shutter speed of 8000 blinks in the display, the image will be ov\
erexposed.
Turn the main dial to set a smaller aperture (larger aperture number) \
so the shutter
speed stops blinking.

5After confirming the shutter speed,
press the shutter button completely
to take the picture.
•If the shutter speed is not blinking,
proper exposure will be obtained.
• Caution: Camera shake may produce
an unsharp picture if the shutter speed
becomes slower than “1/focal length of
the lens in use.”

Apertures are set in 1/3-stop increments. Larger numbers indicate smalle\
r lens apertures.
The following aperture settings are provided in the camera, but the actu\
al aperture range
available depends on the lens in use.

3. Depth-of-Field AE [DEP]
This mode places everything between two freely set points in the fore-
ground and background within the zone of focus, effective for making sur\
e
everyone in a large group picture or everything in a landscape photo is
rendered sharp. After you designate the near and far points in the scene\
,
the camera automatically sets the optimum focus position and the aper-
ture necessary to achieve the required depth of field, then sets the shu\
tter
speed to achieve the correct exposure. The near and far points can be
designated using the selected focusing point in manual focusing point
selection mode, or using the center point in automatic focusing point
selection mode.
•Depth-of-field AE is not possible when the lens’ focus mode switch is\
 set to “ M”.
Make sure the focus mode switch is set to “ AF”.

6Compose the picture and press the
shutter button halfway to set the
aperture and focus for the designat-
ed depth of field.
•The correct aperture value for the des-
ignated depth of field and the corre-
sponding shutter speed are displayed
in both the viewfinder and LCD panel.
• If you remove your finger from the
shutter button, the display changes to
“” and the aperture value.
• The exposure is determined immedi-
ately before the shutter is released.
7Press the shutter button completely
to take the picture.
● Using Automatic Focusing Point Selection Mode
In automatic focusing point selection mode, use the center focusing poin\
t
to designate the near and far focus points. Otherwise, the basic proce-
dure is the same as for “Depth-of-Field AE Using A Manual Focusing
Point Selection Mode”.

							•If the aperture value blinks, the desired depth of field cannot be obtai\
ned. Use a wide-
angle lens or move farther from the subject and repeat steps 4 through 6\
.
• If the shutter speed of 30” and the maximum aperture of the lens blin\
k, the scene will
be underexposed and Depth-of-Field AE cannot be carried out.
• If the shutter speed of 8000 and the minimum aperture of the lens blink,\
 the scene will
be overexposed. Use a neutral density (ND) filter to reduce the amount\
 of light entering
the lens.

Depth-of-Field AE [DEP]
•When using a zoom lens, do not zoom the lens until you finish taking the\
 picture.
• Changing the focusing point during Depth-of-Field AE operation cancels a\
ny previously
set data.
• Flash cannot be used effectively in depth-of-field AE mode. Use of flash\
 will provide the
same result as using flash in Program AE mode.
• When using a lens equipped with a focus range selector (such as the EF3\
00mm f/2.8L
USM), be sure to set it to the maximum range.    
•If the camera sets a slow shutter speed, use a tripod to prevent camera \
shake.
• To cancel Depth-of-Field AE in mid-operation, press the focusing point s\
elector, the
shooting mode selector, the AF mode selector or the metering mode select\
or.   
•For greater depth of field, we recommend using a wide-angle lens.
• For shallow depth of field, place both points 1 and 2 on the same point.\
 This method is
effective for blurring the foreground and background when shooting portr\
aits. Use a
telephoto lens for best effect.

4. Manual Exposure [M]
This mode lets you set both the shutter speed and aperture. Use this
mode when you need complete control of exposure for creative effects or
when using a hand-held exposure meter. 
The main dial sets the shutter speed and the quick control dial sets the\
aperture.   ●Using the Camera’s Built-in
Meter
1While pressing the shooting mode
selector, turn the main dial to the left
or right until “ M” appears in the LCD
panel.    
2Release the shooting mode selec-
tor.
3Set the quick control dial switch to .
4Turn the main dial to the desired
shutter speed and the quick control
dial to the desired aperture.
• The optionally available Command
Back E1 is not equipped with a quick
control dial. When using the Command
Back E1, set the aperture by pressing
the exposure compensation button
and turning the main dial.

Manual Exposure [M]
5Press the shutter button halfway to
focus the subject. “M” and the expo-
sure values are displayed in the
viewfinder. The exposure level indi-
cator at the right of the viewfinder
shows how far the current exposure
setting is from the exposure value
metered by the camera.
6Set the shutter speed and aperture
value as desired while watching the
exposure level display, then press
the shutter button completely to take
the picture.      
In addition to 1/3-stop increments, shutter
speeds and aperture values can also be
input in 1-stop or 1/2-stop increments.   
This function lets you set the aperture
value using the focusing point select but-
ton ( ) in combination with the main
dial.
• The operation method described in step 4
can be changed in six different ways using
various combinations of custom functions 5
and 11 (refer to page 92).     
This custom function lets you switch the
functions of the main dial and quick con-
trol dial.    
•The  indicator shows that the set
exposure will be one stop over the
metered exposure.
