Canon EOS-1DX Af Setting Manualbook page 98

During sporting events or concerts, it is common to
change the camera between horizontal and vertical
positions. The EOS-1D X is equipped with an abundance
of AF frames to choose from - 61 points to be exact. This
provides a high degree of freedom when composing

uppermost left AF point is selected for shooting while
the camera is held in the horizontal position is that when
the grip is switched to the vertical position, the AF point
ends up in the bottommost lower left of the screen. If
you want to keep the entire body of the athlete in the
frame while focusing on their face, you must choose
another AF point.
In situations like this, AF point settings for each position
are especially useful. By selecting [Separate AF pts:
Area+pt] from [Orientation linked AF point], individual
settings for each of the AF area selection modes and the
manually selected AF points can be stored in camera
memory. In the previous case, for example, if you set the
center upper edge AF point beforehand when in the
vertical position with the grip at the top, it is possible to
have the AF point line up with the position of the face
instantly when switching from the horizontal to vertical
position.
