	alent to ISO 200 and maximum selected using Max. Sensitivity option.

	P and A, ISO sensitivity will be adjusted if photo would be overexposed at
On	shutter speed of 1/8 , 0 0 0 or underexposed at value selected for Min. Shutter

	metering system are exceeded (mode S) or when optimum exposure can
	not be achieved at shutter speed and aperture selected by user (mode M).

	fect.

Setup

ISO Auto > On

When a flash is used, foreground subjects may be underexposed in photos taken at slow shutter speeds, in daylight, or against a bright background. Choose a flash mode other than slow sync or select mode A or M and choose a larger aperture.

If a shooting menu bank in which ISO sensitivity has been set to a value greater than 1600 is chosen after On is selected, ISO sensitivity will not be adjusted automatically. ISO sensitiv- ity will also not be adjusted automatically if a Custom Settings bank in which On is selected is chosen after ISO sensitivity has been set to a value over 1600.
