Z: Setting the ISO Speed

About “A” (Auto) ISO Speed

If the ISO speed is set to “A”, the actual ISO speed to be set will be displayed when you press the shutter button halfway. As indicated below, the ISO speed will be set automatically to suit the shooting mode.

Default ISO Speed

Shooting Mode

ISO Speed Setting

d/s/f/a

ISO 100 - 12800

 

 

Bulb

Fixed at ISO 400

 

 

With flash

Fixed at ISO 400*

*If the shooting mode is <d> and bounce flash is set with an external Speedlite, ISO 400-1600 will be set automatically.

*If fill flash results in overexposure, ISO 100 or a higher ISO will be set.

With [8C.Fn I -3: Set ISO speed range] (p.208), the upper and lower limit settings and ISO Auto setting will work as follows.

In d/s/f/ashooting modes

Even if the upper limit is set to H1, H2, or H3 and the lower limit to L, ISO 100-12800 will be set automatically.

If you narrowed the upper and lower limits from the default setting, the ISO speed will be set automatically within the range you have set.

With bulb exposures and flash photography

If ISO 400 is not within the upper and lower limit, the ISO speed will be set close to 400.

Even if [8C.Fn I -3: Set ISO speed range], [8C.Fn I -12: Set shutter

speed range] (p.211), or [8C.Fn I -13: Set aperture value range] (p.211)

is set to limit the settable range, if [8C.Fn I -8: Safety shift] (p.210) is set

to [1: Enable (Tv/Av)] or [2: Enable (ISO speed)], a setting outside the limited range might be set to obtain a correct exposure.
