ISO Sensitivity
ISO sensitivity is a measure of the camera’s sensitivity to light. A greater
value means higher sensitivity. High sensitivity is suitable for shooting
an object in a dark place or a fast-moving object while minimizing
blurring.
ISO sensitivity is controlled using the [ISO Setting] option in the
shooting menu (
G
P.71). When ISO setting is set to [Auto], the camera
automatically changes the sensitivity according to the distance,
brightness, zoom, macro settings, and picture quality/size. Choose
settings other than [Auto] to fix ISO sensitivity at the selected value.
The upper limit for auto ISO sensitivity can be selected using the
[Maximum for ISO Auto] (
G
P.73) in the shooting menu. Note that
this option may not be available in some shooting modes (
G
P.104).
Note
-------------------------------------------------------------------------------------
• When [Auto] is selected for ISO sensitivity, the camera will select an ISO
sensitivity between 100 and the value selected for [Maximum for ISO Auto].
• Images shot with a higher sensitivity may appear grainy.
• When [Auto] is selected for ISO sensitivity, the ISO value displayed when the
shutter release button is pressed halfway may in some instances (for example,
when the flash is used) differ from the value selected when the shutter is
released.
