Hello everybody new here just got my first drone p3s love it but can anyone pls tell me how to zoom in out on the camera when flying thank you

There is no zoom lens on your drone.

To zoom in... fly forward. Zoom out... fly backward.
Where did you get the idea that it zooms?

If you want to zoom in or out near trees the fly with caution. Always take care of your aircraft. It´s not a 30$-copter.
