ISO Sensitivity

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.

 

The camera adjusts ISO sensitivity in response to

q Auto (160–6400)

lighting conditions. ISO sensitivity is adjusted in

x Auto (160–3200)

the range given in brackets; choose larger ranges

w Auto (160–800)

for increased sensitivity when lighting is poor,

smaller ranges to reduce noise (randomly-spaced

 

 

bright pixels, fog, or lines).

 

ISO sensitivity is fixed at the selected value. If 6400

160, 200, 400, 800,

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

1600, 3200, 6400,

four shots each time the shutter-release button is

6400 (NR), 12800,

pressed all the way down and combine them to

12800 (NR)

create a single image processed to reduce the

 

noise that occurs at high sensitivities.

 

 

A“Auto” ISO Sensitivity Options

When auto ISO sensitivity control is in effect, the display shows an ISO AUTO icon and the current ISO sensitivity.

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 1/30 s.
