With flash
*1: Fixed at ISO 400 for bulb exposures.
*2: Depends on the maximum ISO speed limit set.
*3: If fill flash results in overexposure, ISO 100 or a higher ISO speed will be set.
*4: Except in the A, 6, and F modes.
*5: Automatically set within ISO 400 - 1600 (or up to the maximum limit) in the C,
2, 3, 4, 5 and <d> modes if you use bounce flash with an external
Speedlite.
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.266), 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.
3 Setting the Maximum ISO Speed for [ISO Auto]N
For ISO Auto, you can set the maximum ISO speed limit within ISO 400
- 6400.
