focus Area 163

When would you choose one over the other? Tough call. I’d say both
work equally well so you can’t make a bad choice – here the problem is the
features are just too similar to be included in one camera.

5.14.6 LOCK-ON AF
This is an easier-to-invoke version of Center Lock-On AF (originally
described in Section 3.4). It’s better because you’re not restricted to the
center and, once enabled, you don’t have to press any buttons to invoke it.
As a quick reminder: Just like Face Detection will analyze the Live View
video feed to determine a face and then enable only the AF points in front
of that face, Lock-On AF takes it one step further by analyzing the Live
View feed behind the camera’s automatically selected focus point, tries to
identify what the subject is, and then tries to track that subject by enabling
only the AF points in front of that subject as it moves across the frame.

When selecting Lock-On AF in the menu, you can use the Left and Right
joystick positions to choose one of the AF areas previously described:
Wide, Zone, Center, Flexible Spot, or Expanded Flexible Spot.
In use, you focus and shoot on your subject just as you normally would:
just set your focusing point, press the shutter release button halfway, and
immediately after the camera does a focus-lock it will start to track it as it
wanders slowly across the viewfinder.
The best part about this is that Face Detection still works in this mode, and
again, this is an ideal mode when shooting the kids who never stay still.

TIP 1: Lock On AF modes only work in AF-C. If you switch to AF-S then the focus
area goes back to whatever you set minus the “Lock on AF” part.
TIP 2: Lock-On AF is mutually exclusive with Center-Lock-on AF. So make sure
MENU  7  Center Lock-On AF is set to OFF.
TIP 3: Lock-On AF is not available in movie mode (but Center Lock-on AF mode
is.) Got all that? 
