f: Selecting the AF Mode N
This AF mode 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 area selection  mode is set to 61-point automatic selection (p.72), 
the camera first uses the manually-selected AF point to focus. During 
autofocusing, if the subject moves away  from the manually-selected AF point, 
focus tracking continues as  long as the subject is covered by the Area AF frame.
AI Focus AF switches the AF mode from One-Shot AF to AI Servo 
AF automatically if a still subject starts moving.
 After the subject is focused in O ne-Shot AF mode, if the subject 
starts moving, the camera will  detect the movement and change the 
AF mode automatically  to AI Servo AF.
AI Servo AF for Moving Subjects
AI Focus AF for Automatic Switching of AF Mode
 If focus cannot be achieved, the focus confirmation light < o> and AF 
status indicator < e> in the viewfinder will bl ink. If this occurs, the 
picture cannot be taken  even if the shutter button is pressed completely. 
Recompose the picture and try to fo cus again. Or see “When Autofocus 
Fails” (p.110).
  If [z 1: Beep ] is set to [ Disable], the beeper will not sound when focus 
is achieved.
 
After achieving focus with One-Shot AF , you can lock the focus on a subject 
and recompose the shot. This is called “focus lock”. This is conve\
nient when 
you want to focus a subject not covered by the Area AF frame.
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 mode with the Servo mode 
active, the beeper will sound softly. Ho wever, the focus confirmation light 
 in the viewfinder will not light up. No te that focus will not be locked in 
this case.

61 AF points are provided for AF. You can select the AF point(s) suiting 
the scene or subject. Depending on the lens attached to the camera, the number of 
usable AF points and AF point pa tterns will differ. For details, 
see “Lenses and Usable AF Points” on page 79.
You can select one of six AF area selection modes. See the next page 
for the selection procedure.
Single-point Spot AF (Manual 
selection)

viewfinder.
 
In AF point expansion modes, effective 
adjacent AF points will also be displayed.
  In the Zone AF mode, the selected 
zone will be displayed.

 The AF point select ion will change in the 
direction you tilt the . If you press 
<

(or center Zone) will be selected.
 The  dial selects an AF point in the 
horizontal direction, and the <

selects an AF point in  the vertical direction.
 In the Zone AF mode, turning the 
 or < 5> dial will change the 
Zone in a looping sequence.
Pressing the < S> button lights up the AF points that are cross-type AF 
points for high-precision autofocusi ng. The blinking AF points are 
horizontal-line sensitive. For details, see page 78.

zone):   AF
• Single-point Spot AF and Single-point AF:  SEL   (Center)/ SEL AF 
(Off-center)
  With [ 25: Manual AF pt. selec. pattern ], you can set either [Stops at 
AF area edges ] or [Continuous ] (p.102).

Although this is the same as single-point AF, the 
selected AF point  covers a smaller area to 
focus. Effective for pinpoint focusing of 
overlapping subjects such  as an animal in a cage.
Since Spot AF covers a very small area, focusing 
may be difficult during han d-held shooting or for a 
moving subject.
Select one AF point < S> to be used for focusing.
The manually-selected AF point < S> and adjacent AF points < w> 
(above, below, on the left and on the  right) are used to focus. Effective 
when it is difficult to track a moving subject with just one AF point.
With AI Servo AF, the manually-selected AF point < S> must focus-
track the subject first. However, it is  easier to focus the target subject 
than with Zone AF.
With One-Shot AF, when focus is achieved with an expanded AF point, 
the expanded AF point  will also be displayed along with the 
manually-selected AF point < S>.

AF Area Selection ModesN
The manually-selected AF point < S> and adjacent AF points < w> are 
used to focus. The AF point expans ion is larger than with AF point 
expansion (Manual selection  ), so the focusing is executed over a 
wider area. Effective when it is diff icult to track a moving subject with 
just one AF point.
AI Servo AF and One-Shot  AF work in the same way as with AF point 
expansion (Manual selection  ) mode (p.75).
The 61 AF points are divided into ni ne zones for focusing. All the AF 
points in the selected zone are used for the automatic selection of the 
point of focus. It makes achieving focus easier than with single-point AF 
or AF point expansion and it is effective for moving subjects.
However, since it is inclined to fo cus the nearest subject, focusing a 
specific target is harder than with si ngle-point AF or AF point expansion.
The AF point(s) achieving focus is displayed as < S>.

AF Area Selection ModesN
All the AF points are used to focus.  This mode is set automatically in the 
< A > mode.
With One-Shot AF, pressing the shutter button 
halfway will display the AF point(s) < S> that 
achieved focus. If multiple AF points are displayed, 
it means they all have achieved focus. This mode 
tends to focus the nearest subject.
With AI Servo AF, the manually-selected (p.74) AF 
point < S> is used first to achieve focus. The AF 
point(s) achieving focus is displayed as < S>.
61-point automatic selection AF
  With 61-point automa tic selection AF or Zone  AF, the active AF point 
 will keep switching to track th e subject in AI Servo AF mode. 
However, under certain shooting condit ions (such as when the subject is 
small), it may not be able  to track the subject. Also, in low temperatures, 
the tracking resp onse is slower.
  With Single-point Spot AF, focusing  with the Speedlite’s AF-assist beam 
may be difficult.
  If the camera cannot focus with th e EOS-dedicated Speedlite’s AF-assist 
beam, set the AF area selection mo de to Single-point AF (Manual 
selection) and select the ce nter AF point to focus. 
  When the AF point(s) light up, part or all of the viewfinder may light up in 
red. This is a characteristic of AF point display (using liquid crystal).
  In low temperatures, the AF point’s blin king (p.74) may be difficult to see. 
This is a characteristic of AF po int display (using liquid crystal).
 If you set [ 24: Orientation linked AF point] to [   Select separate 
AF points ], you can set the AF area se lection mode and manually-
selected AF point (or Zone) separa tely for vertical and horizontal 
shooting (p.101).
  With [ 24: Selectable AF point ], you can change the number of 
manually selectable AF points (p.98).

The camera’s AF sensor has 61 AF points. The illustration below shows 
the AF sensor pattern corresponding to each AF point. With f/2.8 or 
larger maximum aperture lenses, high-precision AF is possible at the 
viewfinder center.
Depending on the lens attached to the camera, the number of 
usable AF points and AF pattern will differ. For details, see pages 
79 to 84.
About the AF Sensor
The focusing sensor  is geared to obtain higher precision 
focusing with f/2.8 or larger  maximum aperture lenses. A 
diagonal cross pattern makes it  easier to focus subjects 
that may be difficult to focus. It covers the five vertical AF 
points at the center.
The focusing sensor is geared to obtain high-precision 
focusing with f/4 or  larger maximum aper ture lenses. Since 
it has a horizontal pattern,  it can detect vertical lines.
The focusing sensor is geared for f/5.6 or larger maximum 
aperture lenses. Since it has  a horizontal pattern, it can 
detect vertical lines. It covers  three columns of AF points at 
the viewfinder’s center.
The focusing sensor is geared for f/5.6 or larger maximum 
aperture lenses. It can detect ho rizontal lines and covers all 
61 AF points in a vertical pattern.

Lenses and Usable AF Points
Group A
  Although the camera  has 61 AF points, the number of usable AF 
points and focusing patt erns will differ depending on the lens. The 
lenses are thereby classified into  eight groups from A to H. Check 
which group your lens belongs to.
  When using a lens in Groups F to H,  fewer AF points will be usable.
 When you press the < S> button, the AF points  indicated by the   mark 
will blink. (The  / /  AF points will stay lit.)
 
Both “Extender EF1.4x” a nd “Extender EF2x” apply to all the I/II/III models. Regarding new lenses marketed af ter the EOS 5D Mark III, check 
Canon’s Web site to see wh ich group they belong to.
  Some lenses may not be available in certain countries or regions.
