The depth information that can be obtained from differences in angular position/size of objects within cameras' FOV. There's a reason a photo taken with a 28mm doesn't look the same as with a 50 a few steps back.

> a few steps back

Exactly. The steps back change perspective, not the lenses. That’s what I was trying to say above. In the iPhone both lenses are at the same distance to the subject.

A cropped 28mm is indistinguishable from a 50mm or any other larger size, relative photo site receptor size notwithstanding.
But one of the lenses isn't a few steps back from the other.
