Exposure
The camera sets the optimum shutter speed automatically for the aperture value you have 
selected. When you open the aperture (decrease the aperture value), the camera will focus 
within a shorter range (shallow depth of field) and produce a picture with a blurred 
background. When you close the aperture (increase the aperture value), the camera will 
focus within a longer range. Use this mode when you wish to add changes to the background 
representation. Before shooting, you can use the preview function to check how the 
background will look in your picture. 
g“Preview function” (P. 47)
Set the mode dial to A and turn the control dial to set the aperture value.
To check the depth of field with the selected aperture value:
j See “Preview function” (gP. 47).
To change the exposure adjustment interval:
j This can be set in 1/3 EV, 1/2 EV or 1 EV increments. g“EV STEP” (P. 94)
Shutter speed is blinking:
j The optimum exposure cannot be obtained. For details, see “Exposure warning display” (gP. 125).
The camera sets the optimum aperture value automatically for the shutter speed you have 
selected. Set the shutter speed depending on the type of effect you want. A higher shutter 
speed allows you to capture a fast-moving subject without blur, and a slower shutter speed 
blurs a moving subject, creating a feeling of speed or motion.

A fast shutter 
speed can freeze 
a fast action 
scene without any 
blur.
A slow shutter 
speed will blur a 
fast action scene. 
This blurring will 
give the 
impression of 
dynamic motion.
