Flash Function Settings

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.

• Set the balance to [Ambience priority] to lower the proportion of flash output and uses ambient light to produce lifelike shots with a natural mood. Especially useful when shooting dark scenes (indoors, for example). After switching to [P] or [Av] mode, consider setting [Slow synchro] in [: External Speedlite control] to [1/*-30sec. auto]*1 and using slow-sync shooting.
• Set the balance to [Flash priority] to make the flash the main source of light. Useful for reducing shadows on subjects and in the background from ambient light.

1: The value of “1/*” varies depending on current settings.

E-TTL II Flash Metering

• Set to [Eval (FacePrty)] for flash metering suitable for shots of people.
• Set to [Evaluative] for flash metering that emphasizes firing in continuous shooting.
• If [Average] is set, the flash exposure will be averaged for the entire metered scene.

Continuous Flash Control

• 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.

Sync Speed Priority

You can use a faster than normal sync speed in flash photography.

• Available when [Flash mode] is set to [E-TTL II flash metering].
• Flash sync speeds vary as follows when this feature is set to [Enable], depending on the combination of other camera settings.

Camera Setting		Flash Sync Speed (Fastest)
Shutter mode	Cropping/aspect ratio
Elec. 1st-curtain		1/320 sec.
	*	1/400 sec.
Electronic		1/200 sec.
	*	1/320 sec.

Equivalent to APS-C size

Slow Synchro

You can set the flash-sync speed for flash photography in [P] or [Av] mode. Note that the maximum flash sync speed varies depending on the combination of settings for [: Shutter mode] and [: Cropping/aspect ratio].

• 1/*-30sec. auto

  The shutter speed is set automatically in the following range to suit the brightness. High-speed sync is also possible.

  Shutter mode	Cropping/aspect ratio	Shutter Speed
  Mechanical		1/200–30 sec.
  	*	1/250–30 sec.
  Elec. 1st-curtain		1/250–30 sec.
  	*	1/320–30 sec.
  Electronic		1/160–30 sec.
  	*	1/250–30 sec.

  Equivalent to APS-C size

• 1/*-1/60sec. auto

  Prevents a slow shutter speed from being set automatically in low-light conditions. Effective for preventing subject blur and camera shake. Light from the flash provides standard exposure for subjects, but note that backgrounds may be dark.

• 1/* sec. (fixed)

  Shutter speed is fixed as follows, which is more effective in preventing subject blur and camera shake than with [1/*-1/60sec. auto]. However, in low light, the subject's background will come out darker than with [1/*-1/60sec. auto].

  Shutter mode	Cropping/aspect ratio	Shutter Speed
  Mechanical		1/200 sec.
  	*	1/250 sec.
  Elec. 1st-curtain		1/250 sec.
  	*	1/320 sec.
  Electronic		1/160 sec.
  	*	1/250 sec.

Flash Function Settings

The information displayed on the screen, position of display, and available options vary depending on the Speedlite model, its Custom Function settings, the flash mode, and other factors. For details on the Speedlite's functions, refer to the Speedlite's Instruction Manual.

Sample display

Flash mode

You can select the flash mode to suit your desired flash photography.

• [E-TTL II flash metering] is the standard mode of EL/EX series Speedlites for automatic flash photography.
• [Manual flash] is for setting the Speedlite's [Flash output level] yourself.
• Regarding other flash modes, refer to the Instruction Manual of a Speedlite compatible with the respective flash mode.

Wireless functions

You can use radio or optical wireless transmission to shoot with wireless multiple-flash lighting.

For details on wireless flash, refer to the Instruction Manual of a Speedlite compatible with wireless flash photography.

Firing ratio control (RATIO)

With a macro flash, you can set the firing ratio control.

For details on firing ratio control, refer to the Instruction Manual of the macro flash.

Flash zoom (flash coverage)

With Speedlites having a zooming flash head, you can set the flash coverage.

Shutter synchronization

Normally, set this to [First-curtain synchronization] so that the flash fires immediately after the shooting starts.

Set to [Second-curtain synchronization] and use low shutter speeds for natural-looking shots of subject motion trails, such as car headlights.

Set to [High-speed synchronization] for flash photography at higher shutter speeds than the maximum flash sync shutter speed. This is effective when shooting with an open aperture in [Av] mode to blur the background behind subjects outdoors in daylight, for example.

Caution

• When using second-curtain synchronization, set the shutter speed to 1/30 sec. or slower. If the shutter speed is 1/40 sec. or faster, first-curtain synchronization will be applied automatically even if [Second-curtain synchronization] is set.
• Shutter speed is set to 1/8000 when [: Shutter mode] is [Electronic ] and [High-speed synchronization] is selected with a shutter speed of 1/8000 sec. or faster.

Flash exposure compensation

Just as exposure compensation is adjustable, you can also adjust flash output.

Note

• If flash exposure compensation is set with the Speedlite, you cannot set the flash exposure compensation with the camera. If it is set with both the camera and Speedlite, the Speedlite's setting overrides the camera's.

Flash exposure bracketing

Speedlites equipped with flash exposure bracketing (FEB) can change the external flash output automatically as three shots are taken at once.

Flash Custom Function Settings

For details on the Speedlite's Custom Functions, refer to the Instruction Manual of the Speedlite.
