Setting the ISO Speed *
The ISO speed
is
a numeric indication
of
the sensitivity to light. A higher
ISO speed number indicates a higher sensitivity to light. Therefore, a
high ISO speed
is
suited for low light and moving subjects. However,
the image may look more coarse with noise, etc. On the other hand, a
low ISO speed
is
not suited for low light or action shots, but the image
will look cleaner.
The camera can
be
set between ISO 100 and 1600
in
1/3-stop
increments.
ISO Speed
in
the Basic Zone Modes
The ISO speed
is
set automatically within ISO 100-400.
ISO Speed
in
the Creative Zone Modes
ISO 100-1600 can
be
set
in
1/3-stop increments. With C.Fn-08 [ISO
expansion] set to
[1:
On] (p.170), "H" (ISO 3200) can also
be
set.

The current ISO speed will
be
displayed on the LCD panel.
In
a Basic Zone mode, "Auto" will

Setting the ISO Speed.
While looking at the LCD panel or
viewfinder, turn the
<0 > dial.
At higher ISO speeds and higher ambient temperatures, the image will
have more noise.
High temperatures, high ISO speeds, or long exposures may cause
irregular colors
in
the image.
