Its because of "digital zoom" which is not zoom at all.

People don't tend to get 1 foot from "interesting things" for obvious reasons.

So with a cellphone the cameras cannot optically zoom. So the software fakes it by just enlarging a small part of what its sensor picks up and just fills in data using math. Its no different than taking a photograph jpg and zooming in on it.

Looks to me like a screenshot taken from a video that had to be zoomed in.
