is chosen for
Auto ISO sensitivity
in
P
,

,
A
, and

modes,
ISO sensitivity will remain fixed at the value selected by the user
(
0
62). When
On
is chosen, ISO sensitivity will automatically be
adjusted if optimal exposure can not be achieved at the value
selected by the user (ISO sensitivity is adjusted appropriately
when the flash is used). The maximum value for auto ISO
sensitivity can be selected using the
Max. sensitivity
option in the
Auto ISO
sensitivity
menu (choose lower values to prevent noise; the minimum value for auto
ISO sensitivity is automatically set to ISO 100). In modes
P
and
A
, sensitivity will only
be adjusted if underexposure would result at the shutter speed selected for
Min.
shutter spd
. Slower shutter speeds will be used only if optimum exposure can not
be achieved at the ISO sensitivity value selected for
Max. sensitivity
. If the ISO
sensitivity selected by the user is higher than the value selected for
Max. sensitivity
,
the value selected for
Max. sensitivity
will be used instead.
When
On
is selected, the viewfinder shows
ISO-AUTO
and the
information display
ISO-A
. These indictors blink when sensitivity
is altered from the value selected by the user.

Noise is more likely at higher sensitivities. Use the
Noise reduction
option in the shooting
menu to reduce noise (

auto ISO sensitivity control is used in combination with slow sync flash modes (available with
the built-in flash and SB-900, SB-800, SB-600, and SB-400 flash units), possibly preventing the
camera from selecting slow shutter speeds.
