Setting The Iso Speed - Canon EOS-5D Instruction Manual

g Setting the ISO SpeedN
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.
In the <1> (Full Auto) mode, the ISO speed will be set automatically
within ISO 100-400.
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.
When C.Fn-08 [ISO expansion] is set to [1: On] (p.153), "L" (ISO 50)
and "H" (ISO 3200) can also be set.
When you press the <R> button, the viewfinder will show the
current ISO speed or "Auto".
