EOS-1D X 61-Point High-Density Reticular AF, with Cross-type Points
The 61-point AF has numerous cross-type points for great
Not just "cross-type" AF sensors — with f/4 and faster lenses, high-precision cross-type
Up to 41 high-precision cross-type AF points with f/4 or faster lenses, for great subject acquisition and AF accuracy

actual viewfinder display.
Newly developed 61-point AF sensor
With AF coverage of 52% of the horizontal
width of the actual image area, the 61-point AF
system in the EOS-1D X provides tremendous
compositional flexibility. Its beauty goes beyond
what is seen in the viewfinder: superb ability to
initially read and focus upon extremely out-of-
focus subjects; AF down to - 2 EV; link to the
100,000 pixel RGB meter (EOS iTR, during
Automatic AF point selection), and more.
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 take full
advantage of the multi-point AF system and the
AF Configuration Tool which gives incredible
fine-tuning options to AI Servo AF. Of special
note is the AF sensor itself: the high precision
and improved tracking performance of each AF

with everyday horizontal and
vertical subject detail. All 21
central AF points also provide
standard-precision, cross-type
performance with lenses f/5.6
or faster. Finally, twenty off-
center AF points provide high-
precision, cross-type AF when
used with lenses f/4 and faster.

focusing system, most f/2.8~f/4 lenses can
utilize the 41 high-precision cross-type AF
points. With this many high performance f/2.8
and f/4 AF points, it's possible for wide-aperture
lenses to achieve an even higher level of
focusing precision at these AF points than ever
before.
