The camera’s sensitivity to light can be adjusted according to the

amount of light available. The higher the ISO sensitivity, the less

light needed to make an exposure, allowing faster shutter

speeds or smaller apertures.

ISO Sensitivity

Auto (160–6400)

Auto (160–3200)

Auto (160–800)

The camera adjusts ISO sensitivity in response to

lighting conditions. ISO sensitivity is adjusted in

the range given in brackets; choose larger ranges

for increased sensitivity when lighting is poor,

smaller ranges to reduce noise (randomly-spaced

bright pixels, fog, or lines).

160, 200, 400, 800,

1600, 3200, 6400,

6400 (NR), 12800,

12800 (NR)

ISO sensitivity is fixed at the selected value. If 6400

(NR) or 12800 (NR) is selected, the camera will take

four shots each time the shutter-release button is

pressed all the way down and combine them to

create a single image processed to reduce the

noise that occurs at high sensitivities.

“Auto” ISO Sensitivity Options

When auto ISO sensitivity control is in effect,

the display shows an ISO AUTO icon and the

current ISO sensitivity.

6400 (NR)/12800 (NR)

The edges of the image will be cropped out and built-in and optional

flash units and Active D-Lighting can not be used. The desired results

may not be achieved if the camera or subject moves during shooting. If

NEF (RAW) or NEF (RAW) + JPEG fine is selected for image quality, the

picture will be recorded as a fine-quality JPEG image. Only one shot will

be taken if the shutter speed is slower than

30 s.
