Exposure Compensation with ISO Auto
If the ISO speed is set to [AUTO] for manual exposure shooting, you can set exposure compensation () as follows:
- Tap the exposure level indicator
- [: Expo.comp./AEB]
- Turn the control ring while pressing the shutter button halfway ()
- Exposure may not be as expected when ISO Auto is set, because the ISO speed is adjusted to ensure standard exposure for your specified shutter speed and aperture value. In this case, set the exposure compensation.
- Exposure compensation is not applied in flash photography with ISO Auto, even if you have set an exposure compensation amount.
- When ISO Auto is set, you can press the button to lock the ISO speed.
- If you press the button and recompose the shot, you can see the exposure level difference on the exposure level indicator compared to when the button was pressed.
- Any existing exposure compensation amount is maintained if you switch to M mode with ISO Auto after using exposure compensation in P, Tv, or Av mode ().
