To photograph a moving subject, whether it is a child running or a
moving vehicle, use the <5> (Sports) mode.
Use a telephoto lens.
Using a telephoto lens is recommended so you can shoot from afar.
Use the center AF point to focus.
Aim the center AF point over the subject, then press the shutter
button halfway to auto focus. During autofocusing, the beeper will
continue beeping softly. If focus cannot be achieved, the focus
confirmation light <o> will blink.
When you want to take the picture, press the shutter button
completely. If you hold down the shutter button, continuous shooting
(max. approx. 3 shots per sec.) and autofocusing will take effect.

Shooting Tips
Under low light if camera shake is prone to occur, the viewfinder’s shutter
speed display on the bottom left will blink. Hold the camera steady and
shoot.
