| Solution |
Set the ISO speed (image sensor’s sensitivity to light) to suit the ambient light level.
In [  ] mode, the ISO speed is set automatically. Setting the ISO Speed 1. Set the camera's power switch to [ON].
2. Set the Mode Dial to [ P / Tv / Av / M / B ].
3. Press the [  ・ISO ] button.
4. While looking at the LCD panel or the viewfinder, turn the [  ] dial to set the ISO speed.
NOTE
- ISO speed can be set within ISO 100 – 6400 in 1/3-stop increments.
- "A" indicates Auto ISO. The ISO speed will be set automatically
Overview of ISO speed settings
| ISO speed | Shooting Situation
(No flash) | Flash Range |
|---|
| L, 100 - 400 | Sunny outdoors | The higher the ISO speed, the farther the flash range will be. |
| 400 - 1600 | Overcast skies or evening time |
| 1600 - 6400, H | Dark indoors or night |
* High ISO speeds will result in grainier images.
IMPORTANT
- As H (equivalent to ISO 12800) is expanded ISO speed settings, noise (dots of light, banding, etc.) and irregular colors will be more noticeable, and the resolution lower than usual
- As L (equivalent to ISO 50) is an expanded ISO speed setting, the dynamic range will be somewhat narrower than usual.
- If [
 : Highlight tone priority] is set to [Enable], L (equivalent to ISO 50), ISO 100/125/160, and H (equivalent to ISO 12800) cannot be selected.
- Shooting in high temperatures may result in images that look grainier. Long exposures can also cause irregular colors in the image.
- When you shoot at high ISO speeds, noise (such as dots of light and banding) 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 [ISO speed range] to expand the settable ISO speed range from L (equivalent to ISO 50) to H (equivalent to ISO 12800)
Auto ISO
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 - 3200 | ISO 100 - 1600 |
| P / Tv / Av / M | ISO 100 - 6400*1 | ISO 400*1*2*3 |
| B | ISO 400*1 |
*1: The actual ISO speed range depends on the [Minimum] and [Maximum] settings set in [Auto ISO range].
*2: If fill flash will cause overexposure, ISO speed may be reduced, down to a possible minimum of ISO 100 (except in the [M] and [B] modes).
*3: In the [P] mode, if the external Speedlite is set for bounce flash, ISO 400 - ISO 1600 will be set automatically.
