Auto ISO sensitivity control au-
tomatically adjusts ISO sensitiv-
ity if optimal exposure cannot be
achieved at the value selected by
the photographer. If Auto is se-
lected for Minimum shutter speed, the camera will also ad-
just the threshold for auto ISO sensitivity control according
to the focal length of the lens (CPU lenses only), a feature you
will fi nd particularly convenient when using zoom lenses (see
sample photos at right).
To enable auto ISO sensitivity control, select On for ISO
sensitivity settings > Auto ISO sensitivity control in the
shooting menu.
Maximum
sensitivity Choose the maximum value available for auto ISO sen-
sitivity control (200–Hi 2). The minimum is ISO 100.
Minimum
shutter
speed In exposure modes e and g, sensitivity will only be
adjusted if shutter speed would otherwise be slower
than this value (¼ ,000–1 s or
Auto). Highlight Auto and
press
2 to choose whether
the camera gives priority
to shutter speed (Slower)
or ISO sensitivity (Faster)
when Auto is selected.
