I am trying to film my rugby practices with my iPhone and I wonder what is the best lens to capture the whole field without so much fish look.
I noticed that the new iPhone 11 (Pro) has an ultra-wide-angle lens of 120 degrees and, it seems, does not look fisheye. Can I buy a new iPhone Pro and add a lens to get a view of 120 to 170/180 degrees with a limited fisheye?
I really have no idea if the lenses are additive; If you add the same wide-angle lens to a 60-degree field of view lens and compare it with the addition to a 120-degree field of view lens, 120 will be incrementally wider than 60 based on the lens attributes ?
Or should I consider an anamorphic type lens, e.g.
Would this give me the desired look, where I can see almost the entire field assuming that the camera is not so far from the side of the field?
Sorry for the ignorance about the lenses, I really don't know much about how they work or if physics will simply make impossible what I am trying to do, but your help is greatly appreciated.
