Choose the following ISO sensitivity settings:
ISO sensitivity: 200
ISO sensitivity auto
control: On Maximum sensitivity:
6400 Minimum shutter
speed: 1/500 s
In this example, ISO sensitivity will automatically be raised
to a maximum of ISO 6400 if optimal exposure can not be
achieved at ISO 200. In modes
e and g , sensitivity will be
raised only if the shutter speed required for optimal exposure
would be slower than
1 / 500 s (slower speeds will be used if a
speed of 1
/ 500
s would still result in underexposure at ISO
6400).
