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. 35)
Set the mode dial to A and turn the
control dial to set the aperture value.
• The aperture value changes in 1/3 EV
increments as the control dial is turned.
You can also change the step with the
customized settings. g “EV step” (P. 78)

lower value or use a commercially available ND filter (for adjusting the amount of light).
g “ISO k Setting the desired sensitivity to light” (P. 56)
J If the shutter speed indication is blinking when set to a lower speed, set the ISO sensitivity to a
higher value. g “ISO k Setting the desired sensitivity to light” (P. 56)
To check the depth of field with the selected aperture value:
J Refer to “Preview function” (P. 35).
