3 Custom Function Settings

Custom Functions are organized in four groups based on the function type: C.Fn I: Exposure, C.Fn II: Image/Flash exp (exposure)/Disp (Display), C.Fn III: Autofocus/Drive, and C.Fn IV: Operation/Others.

Note that some Custom Function numbers differ from the EOS-1D Mark III’s Custom Functions.

C.Fn I: Exposure

C.Fn I -1 Exposure level increments

0: 1/3-stop set 1/3-stop compensation

1: 1-stop set 1/3-stop compensation

Sets full-stop increments for the shutter speed and aperture.

2:1/2-stop set 1/2-stop compensation

Sets 1/2-stop increments for the shutter speed, aperture, and exposure compensation.

If 2 is set, the viewfinder and the top LCD panel display for 1/2-stop

increments will change as follows: “ ” → “ ”.

C.Fn I -2

ISO speed setting increments

0: 1/3-stop

1: 1-stop

 

 

C.Fn I -3

Set ISO speed range

Disable:

The settable ISO speed range will be 100 - 12800.

Enable:

The settable ISO speed will range from the highest ISO speed

 

to the lowest ISO speed set with [Register].

Register: The highest ISO speed can be registered within 100 to H3 (102400), and the lowest ISO speed can be registered within L (50) to H2 (51200). After entering the settings, select [Apply].

If you want to set the ISO speed range expansion in the same way as other EOS cameras, set the upper limit to [H1], [H2], or [H3], and the lower limit to [L].

Even if C.Fn I -3 is set to L as the lower limit, L cannot be selected during manual exposure movie shooting (ISO 50).
