(C): Hybrid Cross AF Points
Focal plane phase detection AF (vertical detection) +
dedicated phase detection AF (horizontal detection)
(D): Focal plane phase detection points (vertical detection)
* 2 Cross detection focus points achieve high capturing performance by
arranging horizontal detection points and vertical detection points in a
cross shape in the same focusing area. The focus point at the center is also
equipped with a F2.8-sensitive sensor that supports lenses with a minimum
F-value of 2.8 or lower.
Auto focus area of the dedicated phase detection AF
sensor
The dedicated phase detection AF sensor with 79 focus points is
used for auto focusing when a lens that does not support the Hybrid
Phase Detection AF system is attached, or [AF System] is set to
[Ddc Phase AF Only].
• The number of focus points is limited to 61 in the movie shooting mode.

Hint
• Set [Selectable AF Area] to [Only Cross-Type AF] to limit the auto focusing
area to the Hybrid Cross AF Points when the Hybrid Phase Detection AF is
active.

the following situation:
– [Selectable AF Area] is set to [Only Cross-Type AF].
