i: Changing the ISO Speed N
If the ISO speed is set to [AUTO], the 
actual ISO speed to be set will be 
displayed when you press the shutter 
button halfway. As indicated on the next 
page, the ISO speed will be set 
automatically to suit the shooting mode.
ISO [AUTO]
  When you shoot at high ISO speeds,  noise (such as dots of light and 
banding) may become noticeable.
  If you use a high IS O speed and flash to shoot a close subject, 
overexposure may result.
  With ISO 12800 or “ H” (equivalent to ISO 25600), the maximum burst for 
continuous shooting  will greatly decrease.
  As “ H” (equivalent to ISO 25600) is  an expanded ISO speed setting, 
noise (such as dots of lig ht and banding) and irregular colors will be more 
noticeable, and the resolution  will be lower than usual.
  As the maximum ISO speed that can  be set differs between still photo 
shooting and movie shooting (manua l exposure), the ISO speed you set 
may change when you swit ch from still photo shooting to movie shooting. 
Even if you switch back  to still photo shooting, the ISO speed will not 
revert to the original setting.
The maximum ISO speed settable varies dependin g on the setting for [2: 
ISO expansion ] under [54: Custom Functions (C.Fn) ].
• When [ 0: Off] is set: If you set  ISO 12800 during still photo shooting 
and then switch to movie shooting,  ISO speed will be changed to ISO 
6400.
• When [ 1: On] is set: If you set ISO 12800/H (equivalent to ISO 25600) 
during still photo shooting and th en switch to movie shooting, ISO 
speed will be changed to H  (equivalent to ISO 12800).

3  Setting the Maximum ISO Speed for [ISO Auto] N
 When [AUTO] is set, the ISO speed is  indicated in whole-stop 
increments. However, the  ISO speed is actually set in finer increments. 
Therefore, in the image’s shooting in formation (p.266), you may find an 
ISO speed such as 125 or 640 displayed as the ISO speed.
  In the < 2> mode, the ISO speed shown in the table is actually used 
even if ISO 100 is not displayed.

f: Changing the Autofocus Operation N
This AF operation is suited for moving subjects when the focusing 
distance keeps changing. While you hold down the shutter button 
halfway, the subject will be focused continuously.
 The exposure is set at the moment the picture is taken.
  When the AF point selection (p.97)  is automatic, the camera first 
uses the center AF point to focus.  During autofocusing, if the subject 
moves away from the center AF point, focus tracking continues as 
long as the subject is covered by another AF point.
AI Focus AF switches the AF operation from One-Shot AF to AI 
Servo AF automatically if a still subject starts moving.
  After the subject is focused in One-Shot AF operation, if the subject 
starts moving, the camera will detect the movement, change the AF 
operation automatically to AI Se rvo AF, and keep tracking the 
moving subject.
AI Servo AF for Moving Subjects
AI Focus AF for Automatic Switching of AF Operation
  If focus cannot be achieved, the focus confirmation light < o> in the 
viewfinder will blink. If th is occurs, the picture cann ot be taken even if the 
shutter button is presse d completely. Recompose  the picture and try to 
focus again. Or see “Subjects  Difficult to Focus” (p.100).
  If [z 1: Beep ] is set to [ Disable], the beeper will not sound when focus 
is achieved.
With AI Servo AF, the beeper will no t sound even when focus is achieved. 
Also, the focus confirmation light < o> in the viewfinder  will not light up.
When focus is achieved in  the AI Focus AF operation with the Servo mode 
active, the beeper will sound softly. Ho wever, the focus confirmation light 
 in the viewfinder will no t light up. Note that focus will not be locked in 
this case.

 When shooting a portrait up close, use One-Shot AF and focus 
the eyes.
If you focus the eyes first, you can then recompose and the face will 
remain sharp.
  If it is difficult to focus, se lect and use the center AF point.
The center AF point is the most se nsitive among the nine AF points.
 To make it easier to focus a mo ving subject, set the camera to 
automatic AF point selection and AI Servo AF  (p.96).
The center AF point will first be  used to focus the subject. During 
autofocusing, if the subject moves  away from the center AF point, 
focus tracking continues as long as the subject is covered by 
another AF point.
Under low-light conditions, when you  press the shutter button halfway, 
the built-in flash fires a brief burst of  flashes. It illuminates the subject to 
enable easier autofocusing.
Shooting Tips
AF-Assist Beam with the Built-in Flash
  The AF-assist beam will  not be fired in the following shooting modes: 
, , and .
  The AF-assist beam cannot be emit ted with AI Servo AF operation.
  The effective range of the AF-assist beam emitted by the  built-in flash is 
approx. 4 meters/13.1 feet.
  In Creative Zone modes when you  raise the built-in flash with the  
button (p.104), the AF-assist beam will be emitted when necessary. Note 
that depending on the setting for [ 4: AF-assist beam firing] under [54: 
Custom Functions (C.Fn) ], AF beam will not be emitted.

With maximum apertures up to f/5.6:
Cross-type focusing (vertical and horizontal lines detected 
simultaneously) is possible with all AF  points. With certain lenses (see 
below), the off-center AF points will detect only vertical or horizontal 
lines (no cross-type focusing).
With maximum apertures up to f/2.8:*
High-precision cross-type focusing (vertical and horizontal lines 
detected simultaneously) is possible with the center AF point. The 
center AF point is about twice as s ensitive as the other AF points to 
detect vertical and horizontal lines.
The remaining eight AF points enable  cross-type focusing in the same 
way as when using lenses with maximum apertures up to f/5.6.
* Except with the EF28-80mm f/2.8-4L USM and EF50mm f/2.5 Compact Macro.
The following lenses enable only hori zontal-line sensitive focusing with 
the three AF points on the left and the three AF points on the right and 
only vertical-line sensitive focusing  with the top and bottom AF points. 
Cross-type focusing is possible only with the center AF point.

Autofocus can fail to achieve focus (viewfinder’s focus confirmation light 
< o > blinks) with certain subjects such as the following:
  Very low-contrast subjects
(Example: Blue sky, solid-color walls, etc.)
  Subjects in very low light
  Extremely backlit or reflective subjects
(Example: Car with a highly reflective body, etc.)
  Near and far subjects covered by an AF point
(Example: Animal in a cage, etc.)
  Repetitive patterns
(Example: Skyscraper windows,  computer keyboards, etc.)
In such cases, do either of the following:
(1) With One-Shot AF, focus an object at the same distance as the  subject and lock the focus before recomposing (p.61).
(2) Set the lens focus mode switch to < MF> and focus manually.
1Set the lens focus mode switch to
