Flash Control from the Camera Menu

Settings Available on the Flash Function Settings Screen

On the camera's [Flash function settings] or [External flash func. setting] screen, you can configure settings for normal flash photography or radio transmission wireless flash photography.

Main functions you can configure are as follows. Available settings vary depending on flash mode, wireless function settings, and other conditions.

• Flash firing

  To enable flash photography, set to [Enable]. To enable only the AF-assist beam of the Speedlite, set to [Disable].

• E-TTL balance

  You can set your preferred appearance (balance) for flash shots. This setting enables you to adjust the ratio of ambient light to Speedlite light output.

• E-TTL II meter.

  Set to [Eval (FacePrty)] for flash metering suitable for shots of people. High-speed continuous shooting is slower than when [Evaluative] or [Average] is selected. Set to [Evaluative] for flash metering that emphasizes firing in continuous shooting. If [Average] is set, flash exposure is averaged for the entire metered scene. Depending on the scene, flash exposure compensation may be necessary.

• Contin flash ctrl

  Set to [E-TTL each shot] to perform flash metering for each shot. Set to [E-TTL 1st shot] to perform flash metering for only the first shot before continuous shooting. The flash output level for the first shot is applied to all subsequent shots. Useful when prioritizing continuous shooting speed without recomposing shots.

• Slow synchro

  You can set the flash-sync speed for flash photography in (aperture-priority AE) mode.

• Flash mode

  You can choose the flash mode from [E-TTL II flash metering], [Manual flash], or [MULTI flash (stroboscopic)] to suit your desired flash photography.

• Wireless functions

  You can set up radio transmission wireless flash photography. For details, see Radio Transmission Wireless Flash Photography.

• Flash zoom (flash coverage)

  You can set the Speedlite flash coverage. Set to [Auto] for automatic configuration of flash coverage to suit the lens focal length and image sensor size ().

• Shutter synchronization

  As the flash firing timing/method, you can choose from [First-curtain synchronization], [Second-curtain synchronization], or [High-speed synchronization]. For normal flash photography, set to [First-curtain synchronization].

• Flash exposure compensation

  Just as exposure compensation is adjusted, you can also adjust flash output. The amount of flash exposure compensation can be set in a range of ±3 stops, in 1/3-stop increments.

• Flash exposure bracketing

  Enables automatic adjustment to different flash output levels as three shots are taken at once. The setting range is ±3 stops, in 1/3-stop increments.

• Clear settings

  Select [Clear flash settings] or [Clear external flash set.] to restore Speedlite settings to defaults.
