Description
The focus point is selected manually. The camera focuses on the sub-
ject in the selected focus point only. Choose for subjects you can keep
framed in the selected focus point.
The focus point is selected manually. The camera focuses on the subject in
the selected focus point when autofocus is initiated, but if the subject later
leaves the selected point for brief periods, the camera will focus based on
information from surrounding points (the edges of the area surrounding
the selected focus point are shown by small dots, but all 25, 72, or 153 fo-
cus points in the area are used for focus). Choose for low-contrast sub-
jects if the camera has difficulty focusing or for active subjects that are
hard to keep framed in a single point, and in-
crease the number of points if the subject is
moving unpredictably or occupies a large area
of the frame. Choose a setting one level higher
for subjects at the edge of the frame.
The initial focus point is selected manually. While the shutter-release but-
ton is pressed halfway, the camera uses color information to track subjects
that leave the selected focus point and selects new focus points as required.
The camera focuses using all the focus points in a group around the
point selected by the user, reducing the risk of the camera focusing on
the background. Choose for subjects that are difficult to photograph
using a single focus point.
The camera automatically detects the subject and selects the focus
point. Priority is given to the faces of any portrait subjects detected.
