Setting the Flash _

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, a prefiash is fired when you press the shutter button completely. This is to determine the exposure. Then immediately before the exposure ends, the real flash is fired. Therefore, two flashes will be fired. However, with shutter speeds faster than 1/30 sec., 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 "t_ Flash Exposure Compensation" on page 102.

E-TTL II flash metering

For normal flash exposures, set it to [Evaluative]. [Average] is for advanced users. As with an external Speedlite, the metering area is averaged. Flash exposure compensation may be necessary.

Clear flash settings

On the [External flash func. setting] screen, press the < DISP.> button to display the screen to clear the flash settings. When you

select [OK], the settings for the built-in flash and external Speedlite will be cleared.
