ISO Sensitivity
The higher the ISO sensitivity, the less light needed for taking pictures.
The higher the ISO sensitivity, the darker the subject that can be shot. Additionally,
even with subjects of similar brightness, pictures can be taken at faster shutter speeds,
and blurring caused by camera shake and subject movement can be reduced.
• Setting the ISO sensitivity to a high level is effective when shooting dark
subjects, not using the flash, shooting at the telephoto zoom position and
similar situations, but the pictures taken may be slightly grainy.
Types of ISO Sensitivity
The icon for the current setting is displayed on the monitor during shooting
(A8).
• When Auto is selected, the E icon is not displayed at ISO 100, but is displayed
if the ISO sensitivity automatically increases to higher than 100 (A30).
• When Fixed range auto is selected, the U icon and the maximum ISO
sensitivity value are displayed.
B Notes on ISO Sensitivity
• In m (Manual) mode, ISO sensitivity is fixed at ISO 100 if Auto or Fixed range auto is selected.
• This feature may not be used in combination with certain features. See “Features That Cannot Be
Used Simultaneously” (A80) for more information.

M ISO sensitivity
Option Description
ISO sensitivity
•Auto (default setting): The sensitivity is ISO 100 in bright places; in
dark places the camera automatically raises the sensitivity to a
maximum of ISO 1600.
• Fixed range auto
: Choose the range in which the camera
automatically adjusts ISO sensitivity from
ISO 100-400
(default
setting) and
ISO 100-800
. The camera does not raise sensitivity
beyond the maximum value in the selected range. Set the maximum
value for ISO sensitivity to control “grain” that appears in images.
• 100, 200, 400, 800, 1600, 3200, Hi 1 (equivalent to ISO 6400):
ISO sensitivity is locked at the specified value.
Minimum
shutter speed
When the shooting mode is j or l and ISO sensitivity is set to Auto
or Fixed range auto, the shutter speed at which the ISO sensitivity
automatic control starts to function (1/125 to one second) can be set.
The default setting is None. If the exposure is insufficient with the
shutter speed that is set here, the ISO sensitivity is increased
automatically to obtain the correct exposure. If the exposure is still
insufficient even after the ISO sensitivity is increased, the shutter speed
slows down.
