Canon EOS R5 C VR Creator Kit with RF 5.2mm f/2.8 Dual Fisheye Lens - Manual (Page 287)

Servo AF for Moving Subjects
This AF operation is suited for moving subjects. While you hold down the shutter button
halfway, the camera will keep focusing on the subject continuously.
When focus is achieved, the AF point will turn blue. The beeper will not sound even
when focus is achieved.
The exposure is set at the moment the picture is taken.
For details on the continuous shooting speed for continuous shooting, see
Selecting the
Drive Mode .
In [ ] mode, by default, the camera automatically switches to Servo AF in response to
subject movement.
Caution
Depending on the lens used, the distance to the subject and the subject's speed,
the camera may not be able to achieve correct focus.
Zooming during continuous shooting may throw off the focus. Zoom first, then
recompose and shoot.
