When auto ISO sensitivity control is enabled,
the ISO sensitivity and shutter speed
graphics in the information display show the
maximum sensitivity and minimum shutter
speed.
A
Auto ISO Sensitivity Control
Noise (randomly-spaced bright pixels, fog, or lines) is more likely at
higher sensitivities. Use the Noise Reduction option in the shooting
menu to reduce noise (
0 226). Note that ISO sensitivity may be raised
automatically when auto ISO sensitivity control is used in combination
with slow sync flash modes (available with the built-in flash and the
optional flash units listed on page 299), possibly preventing the
camera from selecting slow shutter speeds. Auto ISO sensitivity
control is available only in i-TTL flash control mode (
0 229, 301); in
other modes, the value selected for ISO sensitivity will be used for
pictures taken with the built-in flash or optional flash units.
