Customizing AF Functions
N
EOS iTR* AF performs autofocus by recognizing faces and subject
colors. EOS iTR AF works when the AF area selection mode is set to
Zone AF, Large Zone AF, or Automatic selection AF.
* intelligent Tracking and Recognition: a function that identifies the subject with
the metering sensor in order for the AF points to track it.
u
: EOS iTR AF (Face priority)
The AF point is automatically selected
based not only on AF information, but
also the human face and the subject’s
color information.
With AI Servo AF, the subject is tracked while giving higher priority to
using face information than with the [
EOS iTR AF ] setting. This makes it
easier to keep track of the subject than when only AF information is
available.
In One-Shot AF mode, EOS iTR AF makes focusing on human faces
easier, so you can shoot while concentrating on the composition.
ON: EOS iTR AF
The AF point is automatically selected based not only on AF
information, but also the human face and the subject’s color
information. With AI Servo AF, the subject is tracked giving weight to the
information not only on the face information but also on where (AF
point) the focus was first achieved. The One-Shot AF operation will be
the same as with the [
EOS iTR AF (Face priority) ] setting.
OFF: Disable
AF points are automatically selected based only on AF information.
(The AF does not use the face information or the subject’s color
information.)
Auto AF point selection: EOS iTR AF
