Flash function settings
The information and available functions displayed on the screen will differ depending on the Speedlite, current flash mode, flash Custom Function settings, etc. For details on your Speedlite’s flash functions, refer to the Speedlite’s instruction manual.
Sample display
Flash mode
You can select the flash mode to suit your desired flash shooting.
 | [E-TTL II flash metering] is the standard mode of EX-series Speedlites for automatic flash shooting. The [Manual flash] mode is for setting the Speedlite’s [Flash output level] yourself. For other flash modes, refer to the Speedlite’s instruction manual. |
 | Wireless functions Wireless (multiple) flash shooting is possible with radio or optical transmission. For details on wireless flash, refer to the Speedlite’s instruction manual |
 | Flash zoom (Flash coverage) With Speedlites having a zooming flash head, you can set the flash coverage. Normally, set this to [AUTO] so that the camera will automatically set the flash coverage to match the lens focal length. |
 | Shutter synchronization Normally, set this to [First-curtain synchronization] so that the flash fires immediately after the exposure starts. If [Second-curtain synchronization] is set, the flash will fire right before the shutter closes. When this is combined with a slow shutter speed, you can create a trail of light such as from car headlights at night. With Second-curtain synchronization, two flashes will be fired: Once when you press the shutter button completely, and once immediately before the exposure ends. If [High-speed synchronization] is set, the flash can be used at all shutter speeds. This is especially effective for portraits using fill flash when you want to give priority to the aperture setting. |
 | Flash exposure compensation The same setting as “Flash exposure compensation” on page 190 can be set. For details, refer to the Speedlite’s instruction manual |
 | Flash exposure bracketing Flash exposure bracketing While the flash output is changed automatically, three shots are taken. For details on FEB (Flash Exposure Bracketing), refer to the Speedlite’s instruction manual |
When using second-curtain synchronization, set the shutter speed to 1/25 sec. or slower. If the shutter speed is 1/30 sec. or faster, first-curtain synchronization will be applied even if [Second-curtain synchronization] is set.
By selecting [Clear flash settings], you can revert the flash settings to their defaults.
With an EX-series Speedlite not compatible with flash function settings, you can only set the following: [Flash firing], [E-TTL II meter.], and [Flash exposure compensation] under [Flash function settings]. ([Shutter synchronization] can also be set with certain EX-series Speedlites.)
If flash exposure compensation is set with the Speedlite, you cannot set the flash exposure compensation on the camera (with the 
button or flash function settings). If it is set with the camera and Speedlite, the Speedlite’s setting overrides the camera’s.
