If On is selected for ISO sensitivity settings > Auto ISO sensitivity control in the 
shooting menu, 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).

To display the menus, press the G button. 
Select ISO sensitivity settings in the 
shooting menu, highlight Auto ISO 

sensitivity control and press 2.

Highlight On and press J (if Off is selected, 
ISO sensitivity will remain fixed at the value 
selected by the user).

The maximum value for auto ISO sensitivity 
can be selected using Maximum sensitivity 
(the minimum value for auto ISO sensitivity 
is automatically set to ISO 100; note that if 
the ISO sensitivity selected by the user is 
higher than that chosen for Maximum sensitivity, the value selected by the 
user will be used instead). In modes P and A, sensitivity will only be adjusted if 
underexposure would result at the shutter speed selected for Minimum 

shutter speed (

–1 s, or Auto; in modes S and M, ISO sensitivity will be 

adjusted for optimal exposure at the shutter speed selected by the user). If 

Auto (available only with CPU lenses; equivalent to

s when a non-CPU lens 

is used) is selected, the camera will choose the minimum shutter speed based 
on the focal length of the lens (auto shutter-speed selection can be fine-tuned 
by highlighting Auto and pressing 2; for example, even faster values than 
those usually selected automatically by the camera can be used with telephoto 
lenses to reduce blur). Shutter speeds slower than the minimum value may be 
used if optimum exposure can not be achieved at the ISO sensitivity value 
selected for Maximum sensitivity. Press J to exit when settings are complete.
