a4: AF Point Illumination
Choose whether the active focus point is highlighted in red in the viewfinder. This
option is available in all shooting modes.
a5: Focus Point Wrap-Around
Choose whether focus-point selection “wraps around” from one edge of the
viewfinder to another. This option is available in all shooting modes.
Option Description
Auto
(default)
The selected focus point is automatically highlighted as needed to establish
contrast with the background.
On
The selected focus point is always highlighted, regardless of the brightness of the
background. Depending on the brightness of the background, the selected focus
point may be difficult to see.
Off The selected focus point is not highlighted.
Option Description
Wrap
Focus-point selection “wraps around” from top to
bottom, bottom to top, right to left, and left to right,
so that, for example, pressing
2 when a focus point at
the right edge of the viewfinder display is highlighted
(q) selects the corresponding focus point at the left
edge of the display (w).
No wrap
(default)
The focus-area display is bounded by the outermost focus points so that, for
example, pressing
2 when a focus point at the right edge of the display is selected
has no effect.
