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.
3 Custom Function Settings N
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. 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
For the ISO speed, “ H” (equivalent to ISO 12800 ) will be selectable. 
Note that if [ C.Fn-6: Highlight tone priority] has been set to [ 1: 
Enable ], “H” cannot be set.
C.Fn-3Flash sync. speed in Av (Aperture-priority AE) mode
When you use flash in the  aperture-priority AE mode (Av), you can set the 
flash sync speed.
0: Auto
The flash sync speed is set automatic ally within a range of 1/200 sec. to 
30 sec. to suit the scene’s brightne ss. With an external Speedlite, high-
speed sync is also possible.
1: 1/200-1/60 sec. auto Prevents a slow shutter speed from being  set in low-light conditions. It is 
effective for preventing subject blur  and camera shake. However, while 
the subject will be properly exposed with the flash, the background may \
come out dark.
With setting 1, the exposure  level will be displayed in the viewfinder and on 
the LCD monitor as shown below.

2: 1/200 sec. (fixed)
The flash-sync speed is fixed to 1/ 200 sec. This more effectively 
prevents subject blur and camera s hake than with setting 1. However, 
the background may come out darker than with setting 1.
C.Fn II: Image
C.Fn-4 Long exposure noise reduction
0: Off
1: Auto
For 1 sec. or longer exposure s, noise reduction is performed 
automatically if noise typical of lo ng exposures is detected. This [Auto] 
setting is effective in most cases.
2: On
Noise reduction is performed for all ex posures of 1 sec. or longer. The 
[ On ] setting may be effective for no ise that cannot be detected or 
reduced with the [Auto ] setting.
When 1 or 2 is set, high -speed sync cannot be used with an external 
Speedlite.
  With settings 1 and 2, after the pict ure is taken, the noise reduction 
process may take the same amount of  time as the exposure. You cannot 
take another picture until the nois e reduction process is completed.
  At ISO 1600 and higher, noise might  be more pronounced with setting 2 
than with setting 0 or 1.
  With setting 1 or 2, if  a long exposure is shot with the Live View image 
displayed, “ BUSY” will be displayed during th e noise reduction process. 
The Live View display will not ap pear until the noise reduction is 
completed. (You cannot take another picture.)

C.Fn-5 High ISO speed noise reduction
Reduces the noise generated in the  image. Although noise reduction is 
applied at all ISO speeds, it is particul arly effective at high ISO speeds. At 
low ISO speeds, the noise in the shad ow areas is further reduced. Change 
the setting to suit the noise level.
0: Standard
1: Low
2: Strong
3: Disable
C.Fn-6 Highlight tone priority
0: Disable
1: Enable
Improves the highlight detail. The  dynamic range is expanded from the 
standard 18% gray to bright highli ghts. The gradation between the grays 
and highlights becomes smoother.
  With setting 2, the maximum burst fo r continuous shooting will greatly 
decrease.
  If you playback a  1 or 1 +73 image with the ca mera or print an 
image directly, the effect of the high  ISO speed noise reduction may look 
minimal. You can check the noise reduc tion effect or print noise-reduced 
images with Digital Photo Professi onal (provided software, p.302).
 With setting 1, the Auto Lighting Opti mizer (p.109) is automatically set to 
[ Disable ] and the setting cannot be changed.
  With setting 1, noise ma y become slightly more pronounced than with 
setting 0.
With setting 1, the settable  range will be ISO 200 - 6400.
Also, the  icon will be displayed on  the LCD monitor and in the 
viewfinder when highlight to ne priority is enabled.

C.Fn III: Autofocus/Drive
C.Fn-7 AF-assist beam firing
The AF-assist beam can be em itted by the camera’s built-in flash or by an 
external, EOS-dedicated Speedlite.
0: Enable
If necessary, the AF-assist beam will  be emitted by the built-in flash or 
external Speedlite.
1: Disable The AF-assist beam is not emitted.
2: Enable external flash only If an external Speedlite is attached,  it will emit the AF-assist beam when 
necessary. The camera’s built-in flash  will not fire the AF-assist beam.
3: IR AF assist beam only Among external Speedlites, only thos e which have an infrared AF-assist 
beam will be able to emit the beam.  This prevents any Speedlite which 
uses a series of small flashes (like  the built-in flash) from firing the AF-
assist beam.
With an EX-series Speedl ite equipped with a LED light, the LED light will 
not automatically turn on for AF-assist.
C.Fn-8 Mirror lockup
0: Disable
1: Enable
Prevents mechanical vibrations in  the camera caused by the reflex 
mirror action which can disturb shooti ng with super telephoto lenses or 
close-up (macro) shooting. See  page 122 for the mirror lockup 
procedure.
If the external Speedlite’s [ AF-assist beam firing] Custom Function is set 
to [Disabled ], the Speedlite will not emit th e AF-assist beam even if the 
camera’s C.Fn-7 is set to 0, 2, or 3.

3: AE/AF, no AE lock This is useful for subjects which keep moving and stopping repeatedly. 
In the AI Servo AF mo de, you can press the < A> button to start or stop 
the AI Servo AF operation. The ex posure is set at the moment the 
picture is taken. Thus, the opti mum focusing and exposure will always 
be achieved as you wait for the decisive moment.
