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: Autofocus/Drive, C.Fn IV: Operation/Others.

C.Fn I: Exposure

C.Fn-1 Exposure level increments

0:1/3-stop

1:1/2-stop

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

With setting 1, the exposure level will be displayed in the viewfinder and on the LCD monitor as shown below.

C.Fn-2 ISO expansion

0:Off

1:On

When you set the ISO speed, you will be able to set “H” (equivalent to ISO 12800). Note that if [C.Fn-6: Highlight tone priority] is set to [1: Enable], “H” cannot be set.
