The only feature I cared about the iPhone 5s camera is the dual LED flash to control colour temperature. Everything else is probably in the margin of tolerance among top end models from all brands.Video recording is something I feel the 1020 falls over on. I mean, why no 60fps let alone 120fps. If my ?110 action camera can do 120fps at 720p why can't my ?450 phone/camera hybrid?
(Bluish) white LED colour temperature look sick for portrait. Sticking coloured gel works, maybe. But the problem is guessing which warming filter to use.
