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 increments.
C.Fn-2
ISO expansion
0: Off
1: On
When you set the ISO speed, you can set “H” (equivalent to ISO 
25600) for still photos and “H” (equivalent to ISO 12800) for 
movies. Note that if [C.Fn-3: Highlight tone priority] is set to [1: 
Enable
], “H” cannot be set.
With setting 1, the exposure level will be displayed as shown below.
