Canon EOS R5 C VR Creator Kit with RF 5.2mm f/2.8 Dual Fisheye Lens - Manual (Page 292)

: Large Zone AF: Horizontal
Uses auto selection AF in a horizontal Large Zone AF frame to cover a larger area than
Zone AF, which makes focusing easier than with 1-point AF/Expand AF area and also
effective for moving subjects.
Focusing areas are determined not only based on the nearest subject but also based on a
variety of other conditions such as faces (of people or animals), subject motion, and subject
distance.
AF points in focus are displayed with [
].
