If Off (the default setting) is selected, ISO sensitivity will remain fi xed at

ity option in the shooting menu ( 83).
If On is selected, ISO sensitivity will automatically be adjusted if optimal exposure can not be
achieved at the selected value (fl ash level is adjusted appropriately). The maximum value for
auto ISO sensitivity can be selected using the Max. sensitivity option. In modes P and A,
sensitivity will only be adjusted if underexposure would result at the shutter speed selected
for Min. shutter speed.
When On is selected, the control panel and viewfi nder show ISO-AUTO.
When sensitivity is altered from the value selected by the user, these
indicators blink and the altered value is shown in the viewfi nder (the
indicators do not blink if a fl ash is used.
ISO Auto
Auto ISO control is not available when a value over ISO 1600 is selected for ISO sensitivity. ISO sen-
sitivity can not be set to values over 1600 when On is selected for ISO auto. Foreground subjects
may be underexposed in photos taken with the fl ash at slow shutter speeds, in daylight, or against a
bright background. Choose a fl ash mode other than slow sync or select mode A or M and choose a
larger aperture.
Noise is more likely at higher sensitivities. Use the High ISO NR option in the shooting menu to
reduce noise (
