When On is selected, the viewfinder and 
control panel show ISO-AUTO. When

selected by the user, these indicators 
flash.

You can turn auto ISO sensitivity control on or off by 
pressing the W (S)  button and rotating the sub-
command dial. ISO-AUTO is displayed when auto ISO 
sensitivity control is on.

Noise (randomly-spaced bright pixels, fog, or lines) is more likely at higher sensitivities. Use 
the High ISO NR option in the shooting menu to reduce noise (see page 228). If the shutter 
speed selected for Minimum shutter speed is slower than sync speed selected for Custom 
Setting e1 (Flash sync speed, 0 244), the sync speed will be used as the minimum shutter 
speed for auto ISO sensitivity control during flash photography. Note that ISO sensitivity 
may be raised automatically when auto ISO sensitivity control is used in combination with 
slow sync flash modes (available with the built-in flash and the optional flash units listed on 
page 304), possibly preventing the camera from selecting slow shutter speeds.

When auto ISO sensitivity control is in effect, the adjusted and 
selected values appear in the information display as shown at right.
