ISO Sensitivity
About ISO Sensitivity
The camera’s sensitivity to light (ISO sensitivity) can be adjusted
according to the amount of light available. In general, choosing higher
values allows faster shutter speeds at the same aperture. Choose from
settings of from ISO 64 to 25600. Extended settings of from about 0.3 to
1 EV (ISO 32 equivalent) below ISO 64 and 0.3 to 2 EV (ISO 102400
equivalent) above ISO 25600 are also available.

Adjusting ISO Sensitivity
Hold the S ( Q ) button and rotate the main command dial.

At default settings, changes to ISO
sensitivity are made in increments of
1 /

EV.
The size of the increments can be changed
using Custom Setting b1 [
ISO sensitivity
step value ].
D High ISO Sensitivities
The higher the ISO sensitivity, the less light needed to make an exposure,
allowing pictures to be taken when lighting is poor and helping prevent blur
when the subject is in motion. Note, however, that the higher the sensitivity,
the more likely the picture is to be affected by “noise” in the form of
randomly-spaced bright pixels, fog, or lines.
•
“Noise” can be reduced by enabling high ISO noise reduction. High ISO
noise reduction can be enabled using the [
High ISO NR ] items in the photo
shooting and video recording menus.
