3 Custom Function Settings
C.Fn II -3 Highlight tone priority
0: Disable
1: Enable
Improves the highlight detail. The dynamic range is expanded from the
standard 18% gray to bright highlights. The gradation between the grays
and highlights becomes smoother.
C.Fn II -4 E-TTL II flash metering
0: Evaluative flash metering
Fully automatic flash photography for all conditions, from low light to
daylight fill-flash.
1: Average flash metering
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.
C.Fn II -5 Shutter curtain sync.
0: 1st-curtain synchronization
1: 2nd-curtain synchronization
The flash fires right before the shutter closes. When a slow shutter speed is
set, you can capture a light trail following the subject.
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’s setting.
With setting 1, noise in the shadow areas may be slightly more than usual.
With setting 1, the settable ISO speed range will be 200 - 1600. Also, the ISO speed
displayed on the top LCD panel and in the viewfinder, will have the “0” displayed as a
smaller character such as “
2oo
”. When the image’s shooting info (p.117) is
displayed, the ISO speed’s “0” will also be displayed as a smaller character.
With setting 1, a preflash will be fired for flash metering control right after
you press the shutter button completely. Remember that the main flash will
then fire right before the shutter closes.
