3Setting the FlashN

To prevent the flash from overheating and degrading, avoid firing the MULTI flash more than 10 consecutive times. If you fire the flash 10 times, allow the flash to rest for at least 10 min. before firing the flash again. Some EX-series Speedlites will automatically stop firing after 10 times to protect the flash. If this happens, let the flash rest for at least 15 min.

Shutter sync.

Normally, set this to [1st curtain] so that the flash fires immediately after the exposure starts.

If [2nd curtain] is set, the flash will fire right before the exposure ends. When this is combined with a slow sync speed, you can create a trail of light such as from car headlights at night. With 2nd curtain sync, two flashes will be fired, once when you press the shutter button completely, and once immediately before the exposure ends. However, with shutter speeds faster than 1/30 sec., the 1st curtain sync will automatically take effect.

If an external Speedlite is attached, you can also set [Hi-speed]. For details, see the Speedlite’s instruction manual.

Flash exposure compensation

See “yFlash Exposure ompensation” on page 113.

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.

Wireless setting

See “Using Wireless Flash” on page 119.

Clear flash settings

With the [Built-in flash func. setting] or [External flash func. setting] screen displayed, press the <B> button to display the screen to clear the flash settings. When you select [OK], the settings for the flash will be cleared.
