d: Program AE
If the “ 30” shutter speed and the lowest f/number 
blink, it indicates underexposure.
Increase the ISO speed or use flash.
 If the “ 8000” shutter speed and the highest f/number 
blink, it indicates overexposure.
Lower the ISO speed or use an ND filter (sold 
separately) to reduce the amount of light entering the 
lens.
Differences Between  and  ModesIn the < A> mode, many functions, such as the AF operation and metering 
mode, are set automatically to prevent  spoiled shots. The...

In this mode, you set the shutter speed and the camera automatically 
sets the aperture to obtain the standard exposure matching the 
brightness of the subject. This is called shutter-priority AE. A faster 
shutter speed can freeze the action of a moving subject. A slower 
shutter speed can create a blurred  effect, giving the impression of 
motion.
* < s > stands for Time value.

s: Shutter-Priority AE
If the lowest f/number blinks, it indicates underexposure.
Turn the < 6> dial to set a slower shutter speed until 
the aperture stops blinking or set a higher ISO speed.
 If the highest f/number blinks, it indicates overexposure.
Turn the < 6> dial to set a faster shutter speed until 
the aperture stops blinking or set a lower ISO speed.
Shutter Speed Display
The shutter speeds from “ 8000” to “4” indicate the denominator of the 
fractional shutter speed. For example, “ 125”...

In this mode, you set the desired aperture and the camera sets the 
shutter speed automatically to obtain the standard exposure matching 
the subject brightness. This is called aperture-priority AE. A higher 
f/number (smaller aperture hole) will make more of the foreground and 
background fall within acceptable focus. On the other hand, a lower 
f/number (larger aperture hole) will make less of the foreground and 
background fall within acceptable focus.
* < f > stands for Aperture value (aperture...

f: Aperture-Priority AE
The aperture opening (diaphragm) changes only at the moment when 
the picture is taken. Otherwise, the aperture remains fully open. 
Therefore, when you look at the sc ene through the viewfinder or on the 
LCD monitor, the depth of field will look narrow.
Press the depth-of-field preview button 
to stop down the lens to the current 
aperture setting, and check the depth of 
field (range of acceptable focus).

In this mode, you set both the shutter speed and aperture as desired. To 
determine the exposure, refer to the exposure level indicator in the 
viewfinder or use a commercially-a vailable exposure meter. This 
method is called manual exposure.
* < a> stands for Manual.

a: Manual Exposure
If the ISO speed is set to A (AUTO) for manual exposure shooting, you 
can set exposure compensation (p.200) as follows: •[
z2: Expo.comp./AEB]
• Under [8C.Fn III-4: Custom Controls] with [s: Expo comp 
(hold btn, turn
S)] (p.438).
• Quick Control (p.56)
Exposure Compensa tion with ISO Auto
If ISO Auto is set, the ISO speed setting will change to suit the shutter 
speed and aperture in order to obtain a standard exposure. Therefore, 
you may not obtain the desired exposure effect....

You can select one of four methods to measure the subject brightness. 
In Basic Zone modes, evaluative metering is set automatically. (In the 
<
8: x> and  modes, center-weighted average metering is 
set.)
1Press the  button (9).
2Select the metering mode.

e Center-weighted average metering
The metering is averaged for the entire scene 
with the viewfinder center weighted more 
heavily.
With  q (Evaluative metering), the exposure setting will be locked when you 
press the shutter button halfway and focus is achieved. In the  w (Partial 
metering),  r (Spot metering), and  e (Center-weighted average metering) 
modes, the exposure is set at the moment  the picture is taken. (Pressing the 
shutter button halfway does not...

Exposure compensation can brighten (increased exposure) or darken 
(decreased exposure) the standard exposure set by the camera.
Exposure compensation can be set in the <
d>, , and  shooting 
modes. Although you can set the exposure compensation up to ±5 stops* in 
1/3-stop increments, the exposure compensation indicator in the viewfinder and 
on the LCD panel can only display the setting up to ±3 stops. If you want to set 
the exposure compensation setting beyond ±3 stops, use the Quick Control...
