| Solution |
Set the ISO speed (image sensorâs sensitivity to light) to suit the ambient light level.
In the <  > mode, the ISO speed is automatically set. Setting the ISO Speed 1.Turn on the camera.
- Set the camera's power switch to <ON>.
2. Select the shooting mode.
- Set the Mode Dial to < P >< Tv >< Av >< M >< B >.
 Press the lock release button.
 Turn the Mode Dial.
3. Press the <  > button.
4. Set the ISO speed.
- While looking at the LCD panel or in the viewfinder, turn the <
 > dial.
- ISO speed can be set within ISO 100 - ISO 32000 in 1/3-stop increments.
- "A" indicates ISO Auto. The ISO speed will be set automatically.
ISO Speed Guide
- High ISO speeds will result in grainier images.
| ISO Speed | Shooting Situation
(No flash) | Flash Range |
| L (50), ISO 100 - ISO 400 | Sunny outdoors | The higher the ISO speed, the farther the effective flash range will be. |
| ISO 400 - ISO 1600 | Overcast skies or evening time |
| ISO 1600 - ISO 32000, H1 (51200), H2 (102400) | Dark indoors or night |
IMPORTANT
- As H1 (equivalent to ISO 51200) and H2 (equivalent to ISO 102400) are expanded ISO speed settings, noise (dots of light, banding, etc.) and irregular colors will be more noticeable, and the resolution lower compared with the standard setting.
- As L (equivalent to ISO 50) is an expanded ISO speed setting, the dynamic range will be somewhat narrower compared with the standard setting.
- If [
 : Highlight tone priority] is set to [Enable], L (equivalent to ISO 50), ISO 100/125/160, H1 (equivalent to ISO 51200), and H2 (equivalent to ISO 102400) cannot be selected.
- When shooting with a high ISO speed, high temperature, long exposure, or multiple exposure, image noise (rough grain, dots of light, banding, etc.) and irregular colors may become noticeable.
- When shooting in conditions that produce an extreme amount of noise, such as a combination of high ISO speed, high temperature, and long exposure, images may not be recorded properly.
- If you use a high ISO speed and flash to shoot a close subject, overexposure may result.
REFERENCE
- Under [
 : ISO speed settings], you can use [Range for stills] to expand the settable ISO speed range from L (equivalent to ISO 50) to H1 (equivalent to ISO 51200) and H2 (equivalent to ISO 102400).
ISO Auto
- If the ISO speed is set to "A" (Auto), 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.
| Shooting Mode | ISO Speed Setting |
| No Flash | With Flash |
|
| ISO 100 - ISO 12800 | ISO 100 - ISO 1600 |
| P / Tv / Av / M | ISO 100 - ISO 32000*1 | ISO400*1*2*3 |
| B | ISO400*1 |
*1 : The actual ISO speed range depends on the [Minimum] and [Maximum] settings set in [Auto range].
*2 : If fill-in flash will cause overexposure, ISO 100 or a higher ISO will be set. (Except in the <M> and <B> modes.)
*3 :In the <P> mode, if you use bounce flash with an external Speedlite, ISO 400 - ISO 1600 will be set automatically.
