* 1: Set automatically when the camera shooting mode is set to Basic Zone modes.
* 2: Only Group firing is available.
* 3: Can only be set when the Speedlite is used as a sender in radio transmission wireless operation.
* 4: Only groups set to E-TTL II / E-TTL autoflash.

Flash Exposure Compensation

±3 stops, in 1/3-stop or 1/2-stop*¹ increments.
* The Speedlite's flash exposure compensation takes precedence if flash exposure compensation is performed by both the Speedlite and the camera. Users who prefer to enable flash exposure compensation by the camera should set flash exposure compensation by the Speedlite to 0.
* 1: Corresponds to exposure level increments on the camera.

FEB

±3 stops, in 1/3-stop or 1/2-stop*¹ increments.
* FEB is automatically deactivated after three shots.
* Can be used with flash exposure compensation and FE lock.
* 1: Corresponds to exposure level increments on the camera.

FE Lock

Supported

FE Memory

Supported
• Stores the flash output of E-TTL II / E-TTL autoflash and automatically sets the stored output level if users switch the flash mode to manual flash.
* Flash output may vary slightly between E-TTL autoflash and manual flash.

• Colors may vary between E-TTL autoflash and manual flash under the following conditions:
* When the color temperature of the Speedlite light differs greatly from that of ambient lighting and flash exposure compensation is set toward the negative end.
* When E-TTL balance is set to (Ambience priority).

• Differences in colors between E-TTL autoflash and manual flash may be reduced by taking one of the follow steps:
* Using the provided color filter.
* Setting white balance to an option other than AWB.
