Combined Focus and Exposure
A single tap anywhere on the capture screen activates
the combined Focus/Exposure point. This mode is great
for quick and easy adjustments when shooting.
Separate Focus and Exposure Points
They can also be split by dragging one from the other. In the
spot on the viewfinder where you locate the exposure circle,
exposure is measured and adjusted optimally.
Placing the focus square determines the point where your
picture is focused. A long press anywhere on the screen other
than on these control elements resets the points to the centre.
Lock and Unlock
A long press locks (shown with the small lock symbol)
and unlocks either the Focus Square and Exposure Circle.
This allows you to change and readjust what you see in the
viewfinder without altering your settings of exposure and focus.
Moving a locked focus or exposure control element
causes another automatic metering and saving of the resulting
value. The control element will be locked when adjustment has
finished.
