When [Focus Area] is set to [Wide] or [Zone], the focusing frame may switch between “When focusing on a larger
area” and “When focusing on a smaller area” depending on the subject or situation.
When you attach an A-mount lens with a Mount Adaptor (LA-EA1, LA-EA3 or LA-EA5) (sold separately) and [
AF
System] is set to [Phase Detection AF], the focusing frame for “When focusing on a smaller area” may be displayed.
When focus is achieved automatically based on the whole range of the monitor
When you use a zoom function other than the optical zoom, the [Focus Area] setting is disabled and the focusing
frame is shown by the dotted line. The AF operates with priority on and around the center area.
To move the focus area
You can move the focus area in [Flexible Spot], [Expand Flexible Spot], or [Zone] by operating the multi-selector. If
you assign [Focus Standard] to the center of the multi-selector beforehand, you can move the focusing frame back to
the center of the monitor by pressing the center of the multi-selector.
You can move the focusing frame quickly by touching and dragging it on the monitor. Set [Touch Operation] to [On]
beforehand.
Hint
In the default settings, [Focus Area] is assigned to the C2 button.
