3Setting the Flash

FEB

While the flash output is changed automatically, three flash shots are taken. For details, see the instructions for FEB (Flash Exposure Bracketing) in your Speedlite’s instruction manual.

Flash exposure compensation

The same setting as “Flash exposure compensation” on page 119 can be done.

E-TTL II

For normal flash exposures, set it to [Evaluative].

If [Average] is set, the flash exposure will be averaged for the entire metered scene as with an external metering flash. Since flash exposure compensation may be necessary depending on the scene, this setting is for advanced users.

Zoom

You can adjust the Speedlite’s flash coverage. Normally, set this to [Auto] so that the camera will automatically set the flash coverage to match the lens focal length.

Wireless setting

Wireless flash (with multiple flash units) is possible. For details, see your Speedlite’s instruction manual about wireless flash.

Flash firing

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

When using 2nd-curtain sync, set the shutter speed to 1/50 sec. or slower. If the shutter speed is 1/60 sec. or faster, 1st-curtain sync will be applied even if [2nd curtain] is set.

If flash exposure compensation has already been set with the Speedlite, you cannot use the camera’s <Q> button or Flash function settings menu to set flash exposure compensation. If it is set with both the camera and Speedlite, the Speedlite’s setting overrides the camera’s. The flash function’s [E-TTL II] setting will work together with C.Fn II -5 (p.215). And [Flash firing] will work with C.Fn II -7 (p.216).
