3Custom Function SettingsN

Custom Functions are organized into four groups based on the function type: C.Fn I: Exposure, C.Fn II: Image, C.Fn III: Auto focus/Drive, C.Fn IV: Operation/Others.

C.Fn I: ExposureC.Fn-1 Exposure level increments



Sets 1/2-stop increments for the shutter speed, aperture, exposure compensation, AEB, etc. Effective when you prefer to control the exposure in less fine increments than 1/3-stop increments.

The exposure level will be displayed in the viewfinder and on the LCD monitor as shown below.

C.Fn-2 Flash sync. speed in Av (Aperture-priority AE) mode


The flash sync speed is set automatically within a range of 1/200 sec. to 30 sec. to suit the scene’s brightness.

1:1/200 sec. (fixed)

If you use the <f> mode (aperture-priority AE) for flash photography, the shutter speed will be set to 1/200 sec. You need not worry about camera shake.

(However, night scene or dark backgrounds will look darker in this mode.)
