Pressing the  or  button lights up the AF points that are 
cross-type AF points for high-precis ion autofocusing. The blinking AF 
points are horizontal-line or vertical -line sensitive. For details, see 
pages 127-131.
AF Point Display Indications 
						

							124
 Select one AF point  to be used for focusing.
The AF area is divided into nine focusing zones for focusing. All the AF 
points in the selected zone are used for the automatic AF point 
selection. It is superior to single-point AF in tracking the subject, and it 
is effective for moving subjects.
However, since it is inclined to  focus on the nearest subject, focusing on 
a specific target may be more difficult.
The AF point(s) achieving focus is displayed as <
S>.
The AF area is divided into three  focusing zones (left, center, and right) 
for focusing. Since the focusing area  is larger than with Zone AF and all 
the AF points in the selected zone are used for the automatic AF point 
selection, it is superior to single-poin t AF in tracking the subject, and it is 
effective for moving subjects.
However, since it is inclined to  focus on the nearest subject, focusing on 
a specific target may be more difficult.
The AF point(s) achieving focus is displayed as <
S>.

AF Area Selection Modes
The Area AF frame (entire AF area) is used to focus. This mode is set 
automatically in Basic Zone modes
 (except  and ).
The AF point(s) achieving  focus is displayed as .
 With One-Shot AF, pressing the shutter button 
halfway will display  the AF point(s) <
S> that 
achieved focus. If mul tiple AF points are 
displayed, it means they  all have achieved focus. 
This mode tends to focus on the nearest subject.
 With AI Servo AF, you can set the AI Servo AF’s 
starting position with [
8C.Fn II-11: Initial AFpt, 
o AI Servo AF] (p.422). As long as the Area AF 
frame can track the subject during shooting, 
focusing will continue.
o  45-point Automa tic Selection AF
When AI Servo AF mode is set with 45-point automatic selection AF, 
Large Zone AF, or Zone AF, the active AF point < S> will keep switching 
to track the subject. However, under  certain shooting conditions (such as 
when the subject is small), it ma y not be able to track the subject.
 If a peripheral AF point or a wide-angle lens is used, achieving focus may 
be difficult with an EOS-dedicated, external Speedlite’s AF-assist beam. 
In such a case , use an AF point closer to the center.
 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.
 In low temperatures, the AF point’s display may be difficult to see. This is 
a characteristic of AF point displa y. Also, the tracking response may 
become slower.
With [ 8C.Fn II -10:  Orientation linked AF point ], you can set the AF area 
selection mode + AF point, or only the AF point separately for the horizontal 
and vertical orientations (p.421). 
						

							AF Area Selection Modes

AF Using Color TrackingBy default, AF will be performed based on color tracking.
When the AF area selection mode is set to Zone AF, Large Zone AF, or 
45-point automatic selection AF, focus is achieved as follows:
In One-Shot AF Mode
Focusing on a still human subjec t in the AF area is made easier.
 In AI Servo AF Mode
Focusing on a human subject in the AF area is made easier. If no skin 
tones can be detected, the nearest subject will be focused on. Once focus 
is achieved, AF points are automatically selected so that the camera 
continues to focus on the color of the area it focused on first.
*In [8C.FnII-12 Auto AF pt sel.:Color Tracking], you can set whether to perform 
AF by tracking colors. If [1: Disable] is set, focus is achieved based only on AF 
information (p.422).

The camera’s AF sensor has 45 AF points. The illustration below shows 
the AF sensor pattern corresponding to each AF point. When using 
lenses with a maximum aperture of f/2.8  or faster, high-precision AF is 
possible with the center AF point in the viewfinder.
AF Sensor
The focusing sensor is geared to obtain higher precision 
focusing for lenses with a maximum aperture of f/2.8 or 
faster. A diagonal cross pattern makes it easier to focus on 
subjects difficult for AF. It is provided at the center AF point.
The focusing sensor is geared for lenses with a maximum 
aperture of f/5.6 or faster (and some f/8 lenses). Since it 
has a horizontal pattern, it can detect vertical lines. It 
covers all 45 AF points.

Depending on the lens attached to the camera, the number of usable 
AF points, AF point patterns, the shape of Area AF frame, etc. vary. For 
details, see “Lenses and Usable AF Points” on page 128.

Lenses and Usable AF Points
Group A
 Although the camera has 45 AF points,  the number of usable AF 
points and focusing patterns vary depending on the lens. The 
lenses are thereby classified into eight groups from A to H.
 When using a lens in Groups E to H, fewer AF points will be usable.
 See which group each lens belongs to on pages 132-135.
 Check 
which group the lens in use belongs to.
 The number of available AF point s varies depending on aspect ratio 
settings (p. 146).
 When you press the < S> or < B> button, the AF points indicated by 
the   mark will blink. (The  /  AF points will stay lit.) Regarding 
lighting up or blinking of the AF points, see page 123.
 For the latest “Lens Group Designations” information, check the Canon 
website.
 Some lenses may not be available  in certain countries or regions.
