 Custom Function SettingsN

Fully automatic flash photography for all conditions, from low light 
to daylight fill-flash.

The flash is averaged for the entire area covered by the flash. Since automatic 
flash exposure compensation will not be executed, you may have to set it 
yourself depending on the scene. This also applies if you use FE lock.

When a slow shutter speed is set, you can capture a light trail following the subject. 
The built-in flash or external Speedlite fires the flash right before the shutter closes. 
This Custom Function can be used to obtain 2nd-curtain sync effects even with EX-
series Speedlites which do not have this feature. If the EX-series Speedlite has this 
feature, it will override this Custom Function.

This works in the shutter-priority AE (Tv) and aperture-priority AE (Av) 
modes. If the subject’s brightness changes suddenly and the current 
shutter speed or aperture becomes unsuitable, the shutter speed or 
aperture is shifted automatically to obtain a suitable exposure.

Magnified view is possible while the image is displayed after you 
press the playback button. (p.117)

To magnify the image during the image review, hold down the <l> button and press the 

<u> button. You can also magnify the view in the same procedure as C.Fn-17-0.

When 2nd-curtain sync is used, a preflash will be fired for flash metering control right after you press 
the shutter button completely. Remember that the main flash will fire right before the shutter closes.
