Zoom in or out function of iPhones

Has anyone tried to use zoom in or out function of iPhones during capturing? How does it affect the captured data, and will it enlarge the capture field?

Hi Shane,

Auto focus and zoom are fixed for each camera within the app. Zooming in would change the camera intrinsics.

Hope this helps,
Matt
