C-AF Lens Scanning (KAF Scanner)

Choose whether the camera performs a focus scan. If the camera is unable to focus, it will scan for the focus position by cycling the lens from the minimum focus distance to infinity. You can limit the scanning operation if desired. This option takes effect when [C-AF], [C-AF+TR], [C-AFJ], or [C-AF+TRJ] is selected for [KAF Mode].

Off	The camera will not scan if unable to focus. This prevents focus changing to such an extent that you lose sight of your subject when attempting to track small objects and the like.
On	When unable to focus, the camera scans only once. The camera will not scan again as long as the focus operation continues.

• Regardless of the option selected for [KAF Scanner], the camera will scan once if unable to focus when [S-AF] or [S-AFJ] is selected for [KAF Mode].
