Note that raising sensitivity increases the amount of “noise” visible in the final photograph.
20—ISO Step Value ( pg. 172)
By default, adjustments to sensitivity are made in increments equivalent to
1
/
3
EV (
1
/
3
step).
Custom Setting 20 can be used to set the size of the increments to
1
/
2
or 1 step.
Sensitivity raised by roughly two
steps (2 EV) over ISO 800
Sensitivity raised by roughly one
step (1 EV) over ISO 800
If possible, the current value for sensitivity is maintained when a new ISO step value is selected.
If the value currently selected for sensitivity is not available at the new ISO step value, sensitivity
will be rounded up to the nearest available setting.
31—ISO Boost ( pg. 180)
Sensitivity can be raised by roughly one or two steps over ISO 800 equivalent. If ISO is
selected for Custom Setting 35, or if the ISO button is pressed when Frame Count is se-
lected, the rear control panel will show (sensitivity increased by approximately one step
over ISO 800 equivalent) or (sensitivity increased by approximately two steps over ISO
800 equivalent).
