Pressing the < S> button lights up the AF points that are cross-type AF 
points for high-precision autofocus ing. The blinking AF points are 
horizontal-line or vertical-line sens itive. For details, see pages 99-104.
You can register a frequently-used AF point to the camera.
When you use the button set with the [ 83: Custom Controls] (p.413) 
menu’s detailed settings screens for [ Metering and AF start], [Switch 
to registered AF point ], [Direct AF point selection ], or [Register/
recall shooting func], you can instantly switch from the current AF 
point to the registered AF point.
For details on registeri ng the AF point, see page 418.

For pinpoint focusing over a narrower area than 
with single-point AF (manual selection). Select one 
AF point < > to focus.
Effective for pinpoint focusing or focusing 
overlapping subjects such as an animal in a cage.
Since Single-point Spot AF (manual selection) 
covers a very small area, focusing may be difficult 
during hand-held shooting or for a moving subject.
Select one AF point  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 movi ng subject with just one AF point.
With AI Servo AF, the initial manually-selected AF point < S> must 
focus-track the subject first. However, it is superior to Zone AF in 
focusing on the target subject.
With One-Shot AF, when focus is  achieved with expanded AF points, 
the expanded AF points < S> will also be displayed along with the 
manually-selected AF point < S>.

The manually-selected AF point < S> and surrounding AF points < w> 
are used to focus. The AF point exp ansion 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.95).
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 or AF point expansion in 
achieving focus, and it is ef fective for moving subjects.
However, since it is inclined to  focus on the nearest subject, focusing on 
a specific target may be more diffic ult than with single-point AF or AF 
point expansion.
The AF point(s) achieving focus is displayed as < S>.

AF Area Selection ModesN
The Area AF frame (entire AF area) is used to focus. This mode is set 
automatically in the  mode.
The AF point(s) achieving focus is displayed as < S>.
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 on the nearest subject.
With AI Servo AF, you can set the AI Servo AF’s 
starting position with [ Initial AF pt,   AI Servo 
AF ] (p.128). As long as the Area AF frame can 
track the subject during shooting, focusing will 
continue.

When AI Servo AF mode is set with 61-point automatic selection AF, or 
Zone AF (manual selection of zone), 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 may not be able to track 
the subject. Also, in low temperat ures, the tracking response may 
become slower.
 With Single-point Spot AF (manual selection), focusing with an EOS-
dedicated, external Speedlite’s AF-assist beam may be difficult.
 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. Also, if [ z4: Crop/aspect ratio ] is set, the semi-transparent, 
masked area may light up in red. This is a characteristic of the AF point 
display (using liquid crystal).
 In low temperatures, the AF point’s display may be difficult to see. This is 
a characteristic of AF point display (using liquid crystal).
With [2 4: 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.126).
 With [2 4: Selectable AF point ], you can change the number of 
manually selectable AF points (p.124).

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 100-108.
AF Sensor
These focusing sensors are 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. They cover the five 
AF points vertically aligned at the center.
These focusing sensors are geared to obtain high-precision 
focusing with f/4 or larger maximum aperture lenses. Since 
they have a horizontal pattern, they can detect vertical 
lines.
These focusing sensors are geared for f/5.6 or larger 
maximum aperture lenses. Since they have a horizontal 
pattern, they can detect vertical lines. They cover the three 
columns of AF points at the viewfinder’s center. The center AF 
point and the adjacent AF points at the top and bottom are 
compatible with f/8 or larger maximum-aperture lenses.
These focusing sensors are geared for f/5.6 or larger maximum 
aperture lenses. Since they have a vertical pattern, they can 
detect horizontal lines. They cover all 61 AF points. The center 
AF point and the adjacent AF points on the left and on the right 
are compatible with f/8 or larger maximum-aperture lenses.

Lenses and Usable AF Points
Group A
 Although the camera has 61 AF points,  the number of usable AF 
points and focusing patterns will differ depending on the lens. The 
lenses are thereby classified into nine groups from A to I.
 When using a lens in Groups F to H, fewer AF points will be usable.
 See which group each lens belongs to on pages 105-108. 
Check 
which group the lens in use belongs to.
 When you press the < S> 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 94.
 Regarding new lenses marketed after the EOS 5DS/EOS 5DS R (in the 
first half of 2015), check the Canon website to see which group they 
belong to.
 Some lenses may not be available in certain countries or regions.
