Firmware V2.0
Support for a wider variety of scenes through expanded parameters and
new functions
By combining the ultimate in AF
performance and easy of use, a
wealth of new photographic
possibilities are available.
The EOS-1DX is equipped with a newly-developed
61-Point High-Density Reticular AF. By arranging
the 61 AF points in a dense concentration, the
level of freedom in composition, and tracking
performance of quick-moving subjects is
improved. In combination with AI Servo AF III,
which incorporates a new algorithm ensuring,
accurate focusing on a subject is possible. You can
also effectively set AI Servo AF features using the
AF Configuration Tool. Because you can choose
from six different presets, the correct settings are
always quick and easy, without all the trouble that
comes from adjusting settings for individual
parameters to match the subject or scene.
In the new EOS-1DX firmware V2.0, AF
performance is even further improved and
operability is expanded with a focus on AF. AF
performance in low-light conditions is improved
for the first shot of AI Servo AF, demonstrating its
true ability when shooting subjects in dark
locations. Additionally, this version incorporates
numerous helpful features that assist in shooting
moving subjects, such as newly-added special AF
parameters to deal with speed changes in moving
subjects, and additional functions that can be
assigned to the button customization. This AF
Setting Guidebook introduces effective settings to
make full use of the EOS-1D X high-performance
AF features including new functions of V2.0 of
the firmware. Items with the NEW icon indicate pages with details on the new firmware

of subjects
The [AF Configuration Tool] [Case 1] is the basic
AI Servo AF setting on the EOS-1D X. As its
name indicates, it is versatile and achieves a
high level of tracking performance in a wide
variety of scenes.
Equipped with AI Servo AF III, the EOS-1D X has
improved flexibility in handling a variety of
moving subjects, and superior prediction of
movement for more accurate focusing. Even
with a variety of difficult elements such as
extremely fast movement, sudden changes in
speed, and interruptions by obstacles, AI Servo
AF III overcomes these and is able to capture
the subject.
Case 1 is the recommend setting to start
shooting with, Case 1 will provide great results
when shooting a variety of sports and moving
subjects. When more specific settings for
individual cases are desired, please try Case 2 –
Case 6 to match shooting conditions.
Case 1 can be used to great
advantage when shooting
moving subjects, making it
possible to accurately capture
fast subject.
AF on the EOS-1D X is
equipped with a new
focus tracking algorithm,
AI Servo AF III. It supports
an even greater variety of
subject movement than
before, and by utilizing
the high level tracking
performance of the AI
Servo AF III, and Case 1
configuration setting, it
can handle many different
shooting conditions.

Case 2 is an effective setting for shooting fast
moving subjects when they move away from
the selected AF point, or when obstacles may
momentarily obscure the subject. Sometimes
when the subject moves from the selected AF
point, focus can shift to the background
(resulting in an out of focus subject), similarly
when an obstacle obscures the subject, focus
can shift to the obstacle. By selecting Case 2 in
situations like these, focus will attempt to
continue to track the desired subject. When a
subject moves away from the AF points for an
extended period (such as swimmers doing the
butterfly stroke, or sports where the subject is
hidden for intervals), even better performance
may be achieved by manually setting the
[Tracking sensitivity] parameter to [-2].

Case 3 is the ideal setting for situations when
you want to focus quickly between subjects in
the AF points. In Case 3, the [Tracking
sensitivity] parameter is set to [+1]. As a result,
subjects that come into the AF points will be
focused on more quickly. This setting is most
effective when subjects appear suddenly in the
frame (for example photographing skiers in an
alpine skiing downhill race,). Other shooting
situations, this setting can be extremely effective
is when switching between different subjects
you want to shoot (for example, at the start of
a bicycle road race, when you want to shoot
continuously and switch from cyclist to cyclist
while focusing).
When set to Case 3, if the subject moves away
from the AF points, the camera may quickly
refocus on a different subject or background, in
contrast to Case 2. Therefore, it is recommended
that you use this setting only when you have a
particular objective as indicated above.

Continuously track players as they suddenly slow down and speed up
When shooting sports, there are many
situations where it will be necessary to deal
with fast moving subjects. Subjects suddenly
going from static to moving or sudden stopping
can occur in various sports and situations and it
can be difficult for the AF system to judge
accurately, In these situations, Case 4 is most
effective. With the [Accelerate / decelerate
Tracking] parameter set to [+1], the AI Servo AF
will work to focus track any changes in speed,
including sudden stops and acceleration. This
makes Case 4 the most effective setting for
shooting soccer, rugby, basketball or sports
where there is a lot of running and stopping, as
well as changes of direction. It is also effective
for cornering during motor sports (sudden
deceleration and acceleration).
For example in soccer.
A player dribbling at
h i g h s p e e d s t o p s
suddenly in front of
a defender, changes
direc ti on and then
b e g i n s t o s p r i n t
again. By using Case
4 the AF system reacts
to sudden changes
in spe ed, allowing
c o n t i n u o u s a n d

Case 5 is most effective for subjects with large
amount of movements which could occur in
any direction. This setting works in 61-point
automatic selection AF, Zone AF, and AF point
expansion modes only. In Case 5, [AF pt auto
switching] is set to [+1], when the subject
moves away from the manually selected AF
point (AF points focused on initially with Zone
AF), focusing automatically switches to other AF
points that contain the subject. As a result, even
when the subject continuously leaves the
selected AF point, it is possible to increase the
ratio of photos that are in focus. This setting is
most effective when shooting subjects with
erratic movement such as figure skating,
skateboarding, and inline skating.

are both [+1].
Therefore, Case 6 is an effective setting for
subjects that stop and start suddenly, but also
have erratic movement which could happen in
any direction, it works during Auto selection

only.
Shooting subjects that are most appropriate for
this setting include rhythmic gymnastics which
includes large movements with complete stops.

Subject tracking characteristicsAF Configuration Tool [Parameters]
This setting allows obstacles that pass in front of the sub ject to be ignored, as well as focusing on new subjects
[Locked on] can be effective when an obstacle crosses in front of the subject and when focus jumps to the background,
With the AF Configuration Tool on the EOS-1D
X, not only can you select from Case 1 - Case 6,
but three parameters for each can be adjusted
individually.
[Tracking sensitivity] is the parameter that can
be set to track a subject that the AF point had
been following until a different subject (or
background) got in the way.
The [Locked on: -2/-1] setting excludes subjects
that come into the AF point as obstacles, and
continues to focus on the original subject .
Selecting -2 results in the targeted subject being
tracked for a longer time before focus changes
to subject now in the AF point.
The [Responsive: +1/+2] setting determines that
subjects that come into the AF point are new
subjects to be focused, and quickly focuses. It is
also effective when you want to quickly focus
on subjects that are hidden and appear
suddenly.
An example where [Locked
on: -2/-1] is more effective
When another player, or a
referee crosses in front of the
subject and focus can shift to the
foreground/background
An example where
[Responsive: +1/+2] is
effective
When you want to focus on an
athlete who appears suddenly in
the frame.
Example where the referee momentarily

Wi th t he [Lo cked o n: -1] se tting, the
referee in the foreground is not focused
on, and the AF system continuously tracks
the player.
Example where a skateboarder appeared
suddenly from the far wall. In a situation
like this, setting to [Responsive: +1/+2]
makes it possible to focus even quicker on
the skater that just appeared. (Photo top

Accelerate / decelerate Tracking characteristicsAF Configuration Tool [Parameters]
[-1/-2] is effective for subjects with minor speed changes
A minus setting for subjects with a long shooting distance such as soccer provides more stable focus
[Accel./decel. tracking] is a tracking setting for
subjects that experience changes in speed and move
or stop suddenly. The default setting is [0], which is
best for shooting subjects that move at steady
speeds, or do not experience significant changes in
speeds.
[+1/+2] are best for shooting subjects that suddenly
start or stop moving, or suddenly accelerate or
decelerate. This setting enables the camera to
continue focusing on the desired subject even when
it experiences significant, split-second changes in
speed. For example, the camera becomes less likely to
focus behind an approaching subject that moves
suddenly, and less likely to focus in front of a subject
when it stops suddenly, which would result in a
blurred subject. [+2] can handle greater changes in
speed than [+1].
The newly-added [-1/-2] are effective for shooting far
away subjects with small changes in speed when you
want to focus on minimizing the effects of
obstructions passing by in the foreground of the shot.
Examples where the [-] setting is more effective
Sports with far-away subjects that experience relatively minor changes in
speed, and obstructions that often pass in front of the subject
[Accel./decel tracking] option [-1/2] is a new parameter for shooting in situations
where far-away subjects experience minor changes in speed, and many obstructions
pass by in the foreground. Specifically, this setting is effective for sports with wide
playing fields, such as soccer, when you want to capture action on the far side of the
field. In many cases when photographing such a scene, another athlete moves across
the foreground when the subject you are aiming for is experiencing relatively minor
changes in speed (the relative speed changes become more significant when the
shooting distance is closer). In such a situation, [-1/2] is more effective than a setting
of [0] for foreground obstructions.

AF pt auto switching characteristicsAF Configuration Tool [Parameters]
Set how rapidly the AF point switches to a new AF point for moving subjects
[+1/+2] setting is most effective for sports with lots of movement where the subject can easily move out of the selected AF point
The [AF pt auto switching] parameter is used
for setting characteristics of AF point switching
when the subject has a lot of movements. This
parameter is only for switching between
multiple AF points, so it is unavailable when
using AF area selection modes [Single-point
Spot AF] and [Single-point AF]. The [0] setting is
a standard setting for moderate switching of AF
points. The [+1/+2] settings are used when
shooting subjects with erratic movement which
could happen in any directions. When a
manually selected AF point (AF point being
focused during Zone AF) leaves the subject, it
will rapidly switch to surrounding AF points to
capture the subject. Use the [+] setting when
you want the camera to automatically decide
(switch) to use a new AF point, and the [0]
setting is used when you want to place
emphasis on manually selected AF points to
track the subject.

these AF point modes.
The two types of modes that you can manually
select a single AF point to focus with are
[Single-point Spot AF] and [Single-point AF].
The four modes that can switch automatically
between multiple AF points to capture moving
subjects are AF point expansion (Manual
selection, 4 points [Up, down, left, and right]),
AF point expansion (Manual selection,
surrounding 8 points), Zone AF, and Auto
selection of 61 AF points (during AI Servo AF).
Mode features are explained from P. 29 - 37, so
you can select the mode best suited to your
subject's characteristics and shooting scene.
There are six AF area selection modes to choose from
Single-point AF is an easy to use mode for still

Single-point AF is a mode where one manually selected AF point is used to
focus. For experienced photographers or when it is easy to track the subject
with a single AF point, AI Servo AF can be utilized when continuously
shooting moving subjects, however, this mode is more effective for shooting
still life and landscapes with One-shot AF mode.

AF area selection mode [Spot AF]
Focusing on a small or narrow area
It is possible to focus on pinpoints such as the eye when a helmet is being worn
When set to [Single -point spot AF], a small re ctang le is
displayed inside the manually selected AF point.

[Single-point spot AF] mode can be used to
focus on a small area of the subject. This option
makes it possible to focus on the exact area
even when there is an obstacle near the area
you want to focus on. A common example
when shooting sports is when you want to
focus on the eyes of a rider wearing a helmet
(see photos above). With normal settings, the
AF point can easily get caught on the edge of
the helmet near the eye, resulting in the camera
focusing on this edge. In situations like this,
[Single-point Spot AF] makes it possible to focus
more accurately on the rider’s eye. As [Single-
point Spot AF] only focuses on one very small
area, it is not really suited to capturing fast
moving subjects when set to AI Servo AF and
may take longer to focus than other AF area
selection modes.

[AF point expansion] mode can be used for a wide range of sporting events with erratic movement. [AF point
expansion (Up, down, left, and right)] was able to accurately track the dribbling soccer player.
As switching of the AF point takes place centered on the selected AF point with [AF point expansion], this mode
makes it easy to obtain the desired composition. This high jump athlete was captured with [AF point expansion
(surrounding)].
[Up, down, left, and right] and [surrounding] options can be selected according to the
difficulty of reading the movement, and the relative importance to the central AF point
Hints and tips
When shooting subjects which might be difficult to determine movement, select [surrounding] mode,
and when you want to focus on the area covered by the central (manually selected) AF point it's best to
select the [Up, down, left, and right] mode.
[AF point expansion] is an [AF area selection
mode] that is best selected when shooting
sports. Using this setting shifts the focus point
used from a manually selected AF point, to an
adjacent (up, down, left, and right, or
surrounding) AF point, to aid focus tracking.
When using this setting it is easier to obtain the
desired composition as the subject is captured
centering around the manually selected AF
point. Based on the subject's movement
characteristics, (i.e. likelihood of subject moving
from the selected AF point) and the size of the
subject within the frame, select either [AF point
expansion] or [AF area selection mode]. In
addition, when the subject has a lot of
movement, setting Case 5 or Case 6 from the
AF Configuration Tool is also recommended.

The 61 AF points are divided into three blocks, left, center, and right, and each
has upper, central, and lower zones, and the desired location can be selected
from these nine zones.
Selection can be made from nine focusing zones
With the [Zone AF] mode, one of nine focusing
zones can be selected, and the AF point is
automatically selected from within that zone.
Zone AF differs from [AF point expansion] with
it’s manually selected AF point, which AF
tracking is based around. With Zone AF the
camera decides where to focus on the subject
within the zone, rather than targeting the
subject (area) that you want to follow closely.
This is more suited for situations (the subject
has no obstacles that may block the AF points).
This mode is easy to use when you want to
focus on areas of the subject that are a larger
size, making it possible to easily capture the
appropriate area.

AF area selection mode[Auto selection of 61 AF points]

When using [One-Shot AF], a single AF point is selected automatically from the
61 points. When using [AI Servo AF], AF starts from the manually selected AF
point and then selects the most appropriate from all 61 points.
One-Shot AF AI Servo AF
Capture the subject with an AF point near
the center, and then by moving the camera
to the left, you can compose a photo with
space on the left side of the frame.
Hints and tips
With "AI Ser vo AF" mode, it is possible to
start shooting using a manually selected AF
frame covering the subject. This makes
continue tracking of the subject easy. For
convenience it is possible to select the same
start position for Single Point AF and 61 Point
automatic selection AF and switch between
the two as required.
When using [Auto selection of 61 AF points]
during [AI Servo AF], focusing will start from
the manually selected AF point, the camera will
the automatically change the AF point selecting
from all 61 points as the subject moves. The AF
points are arranged in a wide area so it is useful
for capturing and tracking of subjects, however,
depending on the shooting conditions or if the
subject is small, tracking may not be possible so
caution is necessary. [Auto selection of 61 AF
points] is effective when shooting subjects with
movements that cannot be captured with [AF
point expansion] or [Zone AF] (figure skating
jump scenes for example).
Another effective use is when you want to take
action images for publication/articles with lots
of space in the composition for text etc. In the
examples above shooting began by capturing
the targeted cyclist first with a manually
selected AF point (in the center etc.). From
there, while continuous shooting and moving
the camera (lens) to the left or right, it is
possible to position the lead cyclist off to one
side and include a lot of background (focusing
continues to track the cyclist by automatically
switching AF points).

By increasing number of AF points greater
freedom of composition is possible. The large
number of cross-type AF points improves
tracking performance. And as a result of two-
line AF sensors in a zigzag pattern, tracking
performance is improved for low contrast
subjects as well.
Newly developed 61-point AF sensor
The AF system of the EOS-1D X has many
attractive features such as the high level of
composition freedom with 61 different AF
points, AF area selection modes that utilize the
merits of the multi-point AF system, and
implementation of the AF Configuration Tool
which takes advantage of the improved AI
Servo AF. In addition to these, is the high
precision and improved tracking performance
Most large-aperture lenses with a maximum
aperture of f/2.8, (or lower f-number values) are
in Group A. With this group, the five f/2.8 dual-
cross AF points, and the left and right f/4 and
f/5.6 cross-type AF points (20 points) can be
of each AF point to capture the subject. With
the EOS-1D X AF focusing system, most f/2.8 -
f/4 lenses can utilize the high-performance
41-point cross-type AF points. As Canon
produce a large number of high performance
f/2.8 and f/4 AF points, this makes it possible
for larger aperture lenses to achieve an even
higher level of focusing precision with these AF
points than ever before.
