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 fi 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
,000–1 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.
