As the two cameras have very different focal lengths you get pronounced parallax effect that can be exploited in post.

- ricardobeat 3y agoTwo focal lengths at the same physical distance to the subject have exactly the same perspective (i.e. if you crop them to the same area they will look the same). There is no extra information to be had from that.
- varjag 3y agoThe 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.
- FPGAhacker 3y agoA cropped 28mm is indistinguishable from a 50mm or any other larger size, relative photo site receptor size notwithstanding.

- simondw 3y agoBut one of the lenses isn't a few steps back from the other.
- ricardobeat 3y ago> 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.
