the center operate as dual cross
type AF points at f/2.8, 41 cross-
type AF points are available for
f/2.8-f/4 lenses and the centre
21 AF points serve as cross type
with f/5.6. This makes it possible
to focus with high precision
and high tracking performance
with the many AF points.

AF focusing is possible with 61 points. All
AF area selection modes can be chosen.

Up to 41-point cross-type AF with f/4 lenses, enabling superior tracking performance with most lenses

Group A
41-point cross-type AF, with five f/2.8
dual-cross AF points at the center

Group D
31-point cross-type AF, with one f/2.8 dual-cross
AF point at the center

Group B
41-point cross-type AF, with one f/2.8 dual-cross
AF point at the center

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.

used. There are a total of 41 cross-type points
including the f/5.6 cross-type points. Lenses
with a maximum aperture of f/2.8 in Group B,
will only have a single f/2.8 dual-cross AF point
in the center.
