3 Setting the Maximum ISO Speed for [ISO Auto]N
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.229), you may find an
ISO speed such as 125 or 640 displayed as the ISO speed.
In the <2> mode, the ISO speed shown in the table is actually used
even if ISO 100 is not displayed. COP
