Focuses automatically on a subject in the center of the image. When used
together with the AF lock function, you can compose the image you want.

Allows you to move the focus range finder frame to the desired point on the screen
and focus on an extremely small subject in a narrow area.
On the Flexible Spot shooting screen, you can change the size of the focus range

If the product fails to focus on the single selected point, it uses the focus points
around the flexible spot as the second priority area to achieve focus.
When the shutter button is pressed and held halfway down, the product tracks the
subject within the selected autofocus area. Point the cursor to [Lock-on AF] on the
[Focus Area] setting screen, then select the desired tracking start area using the
left/right sides of the control wheel. You can move the tracking start area to a
desired point by designating the area to be the flexible spot or expand flexible
spot.
On the Flexible Spot shooting screen, you can change the size of the AF range
finder frame by rotating the control wheel.

shooting settings using the control wheel, press the
