I don’t understand why you want to know.
Apple Vision Pro has yet to be released so details are sparse. The marketing pages for Apple Vision Pro say there are at least two cameras facing outward. It’s not clear if there are additional optical cameras facing down at your hands and inward to your eyes, but there are certainly some kind of sensors performing these tasks.
It would be reasonable to expect the main cameras to have autofocus, but this has not been confirmed. Even if it was detailed somewhere publicly, an unreleased product could be changed before it become available. In addition, suppliers can be changed before or during manufacture and sometimes there are multiple suppliers for the same part. So it’s never guaranteed whose parts appears in the product unless you open it.
I guess my question is, why do you want to know about autofocus and why do you want to know about the camera supplier?
