AF area selection mode [Zone AF]
Effective for capturing subjects within a known area
For larger subjects or subjects that move over a larger area
A photo of a moment
of action in fencing
shot with [Zone AF].
In order to focus on
the fencer's facial
area, this shot was
taken by selecting
the upper right zone.
The selected AF points display in [Zone AF].
The 61 AF points are divided into three blocks, left, center, and right, and each
has upper, central, and lower zones, and the desired location can be selected
from these nine zones.
Selection can be made from nine focusing zones
With the [Zone AF] mode, one of nine focusing
zones can be selected, and the AF point is
automatically selected from within that zone.
Zone AF differs from [AF point expansion] with
it’s manually selected AF point, which AF tracking is based around. With Zone AF the
camera decides where to focus on the subject
within the zone, rather than targeting the
subject (area) that you want to follow closely.
This is more suited for situations (the subject has no obstacles that may block the AF points).
This mode is easy to use when you want to
focus on areas of the subject that are a larger
size, making it possible to easily capture the
appropriate area.
Blue color of focus point is for illustration.
