q Metering Modes
e Center-weighted average 
metering
The metering is weighted at the center 
and then averaged for the entire scene.
With multiple spot meter readings, you can see the relative exposure levels of multiple areas in the picture and set the exposure to obtain the desired result.
1Set the metering mode to  r spot metering.
2Press the < I> button. (8 )
  Aim the spot metering circle over the area where you want a 
relative exposure reading, then press the < I> button. 
X
On the right of the viewfinder, the relative exposure level will be displayed for the spot meter 
reading taken. For the exposure, the average of the spot meter readings will be set.
 While referring to the exposure level indicator’s three spot metering marks, you can set 
the exposure compensation to set the final exposure and obtain the desired result.
Multi-Spot Metering
  You can take up to eight spot meter readings for one picture.
  The exposure setting obtained with multi-spot meter readings will be 
canceled in the following cases:
• After taking the last spot meter reading, 16 seconds elapse.
• 
You pressed the , , , , , or  button.• After taking the picture, you let go of the shutter button.
 Multi-spot metering is possible even with  AF point-linked spot metering (C.Fn I -7-1).

5Take the picture.
  Compose the shot and press the 
shutter button completely.
  If “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 re duce the amount of  light entering 
the lens.
  If the focus confirmation light < o> blinks, the shutter will lock and a 
picture cannot be taken. (p.86)
  When automatic AF point selection is used (p.84), multiple AF points 
may flash simultaneously  when focus is achieved.
About Program Shift In Program AE mode, you can freely change the shutter speed and 
aperture combination (Program) set by the camera while maintaining the 
same exposure. This is called Program Shift.
  To do this, press the shutter button down halfway, then turn the < 6> 
dial until the desired shutter speed or aperture value is displayed.
  Program Shift is canceled automatically after the picture is taken.
  Program Shift cannot be used with flash.

In this mode, you set the shutter speed and the camera automatically 
sets the aperture to obtain the correct exposure matching the 
brightness of the subject. This is called shutter-priority AE. 
A faster shutter speed can freeze th e action or moving subject. Or a 
slower shutter speed can create a bl urred effect, giving the impression 
of motion.
* < s > stands for Time value.
1Select < s>.
 Press the < W> button and turn 
the < 6/5 > dial to select < s>.
2Set the desired shutter speed.

 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, “ 125” indicates 1/125 sec. Also, “ 05” 
indicates 0.5 sec. and “ 15” is 15 sec.  
						

							
96
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.
*  stands for Aperture value (aperture opening).
1Select < f>.

Press the depth-of-field preview button 
to stop down to the current aperture 
setting. You can check the depth of field 
(range of acceptable focus) through the 
viewfinder.
Depth-of-Field Preview
 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 set a smaller 
aperture (larger f/number) until the blinking 
stops or set a lower ISO speed.
Aperture Display
The larger the f/number, the smaller the aperture opening will be. The 
aperture values displayed will differ dep ending on the lens. If no lens is 
attached to the camera, “ 00” will be displayed for the aperture value.
  A higher f/number will make more of the foreground and background fall 
within acceptable focus. However, the viewfinder will look darker.
  If the depth of field is difficult to discern, hold down the depth-of-field 
preview button while turning the < 6> dial.
  The exposure will be locked (AE lock) while the depth-of-field preview 
button is pressed.

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.
1Hold down the < W> and 
< o > buttons 
simultaneously.
