Nonsense. All the parts of a camera work together to facilitate captures, so claiming "cameras are really disappointing" without having yet used the new iPhone 15 Pro cameras is total nonsense. Absurd even. New chip, new tele lens, etc. are obvious hardware changes, and the software, OIS, etc. are no doubt also new.
Make your "cameras are really disappointing" claims after testing the new iPhone 15 Pro Max camera. Until then this thread OP is nonsense.
Well I could (and maybe should) have called the thread „camera hardware is disappointing“ because 5 of the 6 cameras are actually absolutely identical to the 14 Pro (and the one that is changed is for me personally a step in the wrong direction). A new chip - I assume you mean the A17 - is not „photography hardware“, sorry; and there is literally no „etc.“ 😂
As I already said in this thread (if you had cared to read everything), of course software is very important, too, but, to quote myself, computational wizardry only goes so far and hardware progress cannot be dismissed. And just for you I‘ll say/repeat that IMHO the iPhone Pro models are wonderful smartphone cameras and far and away the best you can buy. Which doesn‘t mean that a meagre year for new hardware can‘t be criticized.
