Can the EOS RP track a subject while you recompose in Servo AF?

On the Canon EOS RP, One Shot AF lets you focus and recompose, but in Servo AF the camera normally keeps focusing at the currently selected AF point. Is there a way to start on a subject, then have Servo AF continue tracking that subject as I recompose, instead of refocusing on whatever moves under the AF point? If so, what AF settings enable this?

Yes, this is possible.
First, select the servo AF mode.
Then, select AF point to face detect + tracking.
Now with the previous settings, you won't see the AF point anymore in the viewfinder or the LCD because it's doing face detect.
Then, set custom functions II-7: initial servo AF point for face detect + tracking to the setting value 2 (AF point set for other modes).
Now the AF point became visible again.
This way, the subject at the autofocus point will be selected for tracking AF. I think the face detection will probably be disabled in this custom functions setting value.
When recomposing the picture, the camera will use sophisticated algorithms to track the subject, even if the position of the subject within the frame changes.
The only drawback with these particular settings is that the level indicator is not visible anymore, so you may end up with a shot that is not perfectly level.

Yes. On the EOS RP, use Servo AF together with the camera’s tracking AF mode rather than a fixed AF point.
A working setup is:
- Set AF operation to Servo AF
- Set AF method to Face Detect + Tracking
- In Custom Functions, set “Initial Servo AF point for Face Detect + Tracking” to use the AF point set for other modes
With that configuration, you can place the AF point over your subject to start focus, and the camera will then track that subject as you recompose instead of simply focusing whatever is under the AF point afterward.
In other words, the RP can do what you want, but it’s done through tracking AF, not traditional focus-and-recompose behavior. Tracking performance will depend on how well the camera can recognize and follow the subject.
