I'm trying to film my rugby practices with my iPhone and wondering what is the best lens to use to capture the entire field without much that fish eye look?
I noticed that the new iPhone 11 (Pro) has a 120 degree ultra wide angle lens and from the looks of it it doesn't look fish eyed at all. Could I buy a new iPhone Pro and add a lens to it to get from 120 to 170 / 180 degrees of view with only limited fish eyeing?
I really have no idea whether lenses are additive where if you add the same wide angle lens to a 60 degree field of view lens and compare it to adding it to a 120 degree field of view lens, will the 120 just be incrementally wider than the 60 based on the attributes of the lens?
Or should I consider an anamorphic type lens e.g. https://www.shopmoment.com/shop/anamorphic-lens Would this give me the desired look, where I can see almost all the field assuming the camera isn't that far away from the side of the pitch.
Apologies for the ignorance about lenses, really don't know a lot about how they work or whether physics will just make what I'm trying to do impossible, but your help is much appreciated.
