Reducing Noise and Blur: Auto ISO Sensitivity Control

When On is selected for ISO sensitivity

settings > Auto ISO sensitivity control

in the shooting menu, the camera au-

tomatically adjusts ISO sensitivity if op-

timal exposure can not be achieved at

the value selected by the user.

Auto ISO sensitivity control can be  ne-

tuned using the following options.

Maximum sensitivity: Choose the maxi-

mum value available for auto ISO sen-

sitivity control (200–Hi 4). The mini-

mum is ISO 100.

•

Minimum shutter speed: In exposure modes e and g, sensitiv-

ity will only be adjusted if shutter speed would otherwise

be slower than this value (¼ –1 s or Auto). If Auto is

selected, the camera will adjust the threshold for auto

ISO sensitivity control according to the focal length of

the lens.

Tips

We recommend that you use matrix metering (L) and

choose exposure mode e or g. Exposure compensation

can be used.
