The AF frame appears as follows when the shutter button is pressed halfway.

-Green: Shooting preparations complete

-Yellow: Focusing difficulty (AiAF set to [Off])

The following occurs when [Face Detect] is selected.

-Up to three AF frames display. At this point, the frame the camera judges to be the main subject appears in white while the others appear in gray. Pressing the shutter button halfway displays up to 9 green AF frames.

-If no white frame displays and all the frames appear in gray, images will be shot using the [On] option rather than [Face Detect].

-The camera may mistakenly identify non-human subjects as a face. If this occurs, switch to the [On] or [Off] option.

-When a face is not detected, images will be shot using the [On] option.
