Active AF

While you press [Shutter] halfway, the camera automatically detects the
subject's movements and switches between Single AF and Continuous
AF. It fixes the focus on the subject when the subject gets far from the
camera (Single AF). It continues to focus automatically when the subject
gets closer to the camera (Continuous AF). This mode is recommended for
shooting subjects that are moving unpredictably.
This option is not available when the camera is recording a video.

Manual focus

You can manually focus on a subject by rotating the focus ring on the lens.
The MF Assist function lets you easily bring a subject into focus. While you
are rotating the focus ring, the focus area is magnified. When you use the
Focus Peaking function, the color you selected appears on the focused
subject. This mode is recommended for shooting a subject similar in color
to the background, a night scene, or fireworks.
If you use this function, you cannot set Touch AF, AF Area, Face Detection, and
Link AE to AF Point options.
