Settings Available on the Flash Function Settings Screen

• EOS DIGITAL cameras released in and after 2012

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

  Although the EOS REBEL T100/4000D/3000D, EOS REBEL T7/1500D/2000D, EOS REBEL T6/1300D and EOS REBEL T5/1200D was released from 2012 onwards, the settable functions are the same as with the EOS DIGITAL cameras released from 2007 to 2011.

• EOS DIGITAL cameras released from 2007 to 2011

  EOS-1Ds Mark III, EOS-1D Mark IV/III, EOS 5D Mark II, EOS 7D, EOS 60D, EOS 50D, EOS 40D, EOS REBEL T3i/600D, EOS REBEL T2i/550D, EOS REBEL T1i/500D, EOS REBEL XSi/450D, EOS REBEL T3/1100D, EOS REBEL XS/1000D

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

Main functions you can configure are as follows. The settings available vary by the camera used, flash mode, and wireless function settings, etc.

• 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.

• Flash sync. speed in Av mode

  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], [MULTI flash (stroboscopic)], [Auto external flash metering], [Manual external flash metering], or [Continuous shooting priority mode] to suit your desired flash photography.

• Wireless functions

  You can set radio transmission wireless flash shooting and optical transmission wireless flash shooting. For details, refer to "Radio Transmission Wireless Flash Photography" and "Optical Transmission Wireless Flash Shooting".

• 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 settings] to restore Speedlite settings to defaults.
