d: Program AE
 If the “ 30” shutter speed and the maximum aperture 
blink, it indicates underexposure.
Increase the ISO speed or use flash.
 If the “ 8000” shutter speed and the minimum aperture 
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 < d> and < 1> (Full Auto)With < 1>, many functions such the AF mode, drive mode, and built-in 
flash are set automatically to prevent  spoiled...

In this mode, you set the shutter speed and the camera automatically 
sets the aperture to obtain the correct exposure suiting the brightness of 
the subject. This is called shutter-priority AE. A faster shutter speed can 
freeze the action or moving subjec t. Or a slower shutter speed can 
create a blurred effect, giving the impression of motion.
* < s > stands for Time value.
1Set the Mode Dial to < s>.
2Set the desired shutter speed.

s: Shutter-Priority AE
If the maximum aperture 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 minimum aperture 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, “...

104
In this mode, you set the desired aperture and the camera sets the 
shutter speed automatically to obtain the correct exposure suiting 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
Press the depth-of-field preview button 
to stop down the lens to the current 
aperture setting. You can check the 
depth of field (range of acceptable focus) 
through the viewfinder.

If the “ 30” shutter speed blinks, it indicates 
underexposure.
Turn the < 6> dial to set a larger aperture (smaller f/
number) until the blinking stops or set a higher ISO 
speed.
 If the “ 8000” shutter speed blinks, it indicates 
overexposure.
Turn the < 6> dial to...

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-available handheld exposure meter. 
This method is called manual exposure.
*  stands for Manual.
1Set the Mode Dial to < a>.
2Set the ISO speed (p.64).
3Set the shutter speed and aperture.
 To set the shutter speed, turn the 
 dial.

You can select one of four methods to measure the subject brightness. In fully-automatic modes (1/C), evaluative metering is set automatically.
1Press the  button. (9 )
2Select the metering mode.
While looking at the LCD panel, turn 
the < 6> dial.
q Evaluative metering
This is a general-purpose metering mode suited for 
portraits and even backlit subjects. The camera 
sets the exposure automatically to suit the scene.

Exposure compensation can increase (brighter) or decrease (darker) 
the standard exposure set by the camera.
Although you can set the exposure com pensation up to ±5 stops in 1/3-
stop increments, the exposure compensation indicator on the LCD 
panel and in the viewfinder can only display the setting up to ±3 stops. If 
you want to set the exposure compensation setting beyond ±3 stops, 
you should follow the instructions for [ 2 Exp. comp./AEB ] on the next 
page.

By changing the shutter speed or aperture automatically, the camera 
brackets the exposure up to ±3 stops in 1/3-stop increments for three 
successive shots. This is called AEB.
* AEB stands for Auto Exposure Bracketing.
1Select [Expo. comp./AEB].
Under the [2 ] tab, select [Expo. 
comp./AEB ], then press < 0>.
2Set the AEB amount.
Turn the  dial to set the AEB amount.
You can set the exposure compensation 
amount with the <
5> dial. If AEB is 
combined with exposure compensation, 
AEB will be...

Use AE lock when the area of focus is to be different from the exposure 
metering area or when you want to take multiple shots at the same exposure 
setting. Press the <
A> button to lock the exposure, then recompose and 
take the shot. This is called AE lock. It is effective for backlit subjects.
