Sensitivity is a measure of how quickly the camera reacts to light. The higher the sensitivity,
the less light needed to make an exposure. Although a high ISO rating is suitable for shooting
pictures of subjects in action or in poor lighting, high sensitivity is often associated with
"noise" - randomly spaced, brightly colored pixels concentrated in dark parts of the image.
ISO sensitivity
• Auto (default setting): Sensitivity is ISO 160 in bright places; in dark places the
camera automatically raises sensitivity to a maximum of ISO 800.
• High ISO sensitivity auto: The ISO sensitivity is set automatically within the
range of ISO 160 to 1600 according to the brightness of the subject.
• Fixed range auto: Choose the range in which the camera automatically adjusts
ISO sensitivity, from ISO 160-200 (default setting) or ISO 160-400. The camera
will not raise sensitivity beyond the maximum value in the selected range. Set the
maximum value for ISO sensitivity for effective control over the amount of "grain"
that appears in images.
• 160, 200, 400, 800, 1600, 3200: ISO sensitivity will be locked at the specified value.

Minimum shutter speed

When the shooting mode is A or C and ISO sensitivity is set to Auto, High ISO
sensitivity auto, or Fixed range auto, the shutter speed at which the ISO
sensitivity automatic control starts to function (1/125 to one second) is 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.
At settings other than Auto, the current setting is displayed in the monitor (A8).
• If Auto is selected and the sensitivity is raised above ISO 160, the E icon will
be displayed (A36).
• V is displayed when High ISO sensitivity auto is selected, and U and the
maximum ISO sensitivity value are displayed when Fixed range auto is selected.

Notes on ISO Sensitivity
• In D (manual) mode, ISO sensitivity will be fixed at ISO 160 if Auto, High ISO sensitivity auto or
Fixed range auto is selected.
• When the ISO sensitivity is ISO 800, the slowest shutter speed is restricted to four seconds, when
ISO 1600, restricted to two seconds, and when ISO 3200, restricted to one second.
• This feature cannot be used simultaneously with certain features. See "Functions that Cannot be
Applied Simultaneously" (A96) for more information.
