Focus Point Selection
The camera offers a choice of eleven focus points that together cover a wide area of
the frame. At the default settings, the camera chooses the focus point automatically
or focuses on subject in the center focus point. The focus point can also be selected
manually to compose photographs with the main subject positioned almost
anywhere in the frame.
1
Choose single- or dynamic-area AF.
At default settings, the focus point is selected
automatically in
i, j, k, l, o, P, S, A, and M modes. To
enable manual focus-point selection in these modes,
select Single point, Dynamic area, or 3D-tracking (11
points) for Custom Setting a1 (AF-area mode; pg. 173).
2
Set the focus selector lock to “ J“.
Set the focus selector lock to the “ J” position.
This allows the multi selector to be used to
select the focus point.
3
Select the focus point.
Use the multi selector to select the focus point
in the viewfinder or control panel while the
exposure meters are active (pg. 35). The focus
selector lock can be returned to the “L” (locked)
position following selection to prevent the
selected focus point from changing when the
multi selector is pressed.
