Intelligent Tracking and Recognition.*
Using actual color information gathered by the
camera's 100,000 pixel RGB metering system,
the AF system can track a subject using its size,
shape and color information — constantly
updating the active AF point(s), as it focus-
tracks it across the AF array.
* EOS iTR is selectable in the 4th AF menu. Disabled by default, it
can be easily activated by the EOS-1D X user. When off, only
subject sharpness info is used to automatically select AF points
during [Automatic AF point selection].
