When [AUTO] is set, the ISO speed is indicated in whole-stop increments.
However, the ISO speed is actually set in finer increments. Therefore, in the
image's shooting information (p.270), you may find an ISO speed such as
125 or 640 displayed as the ISO speed.
For ISO Auto, you can set the maximum ISO speed limit within ISO 400
- 6400.
Under the [1_12] tab, select [ISO Auto],
then press <SET>. Select the ISO
speed, then press <SET>.
