I would like to see larger camera sensors on the ultra wide and the telephoto, along with a longer telephoto zoom.
Being a photographer, what has always been the most impressive about the iPhone has been its main wide sensor. Even when comparing older 12MP iPhone sensors to their competitors that were using QB binned layouts and such, the wide sensor managed to really hold up. Quite often I was preferring photos taken from the iPhone’s wide sensor over the Pixel 6 and Galaxy S22 family.
However, the exact opposite is true for the telephoto and ultra wide cameras that have been on iPhones, for the longest time. The ultra wide on the 11 and 12 family is so violently noisy that even in good lighting conditions it’s hard to get a solid photo. The 13 at least made it usable in decent lighting but the indoor and nighttime performance were still what I expected out of a $300 budget phone, not a flagship. Similar sentiments can be shared with the telephoto. The 14 improved both greatly but they still need MUCH better sensors to come half as close to the telephotos and ultrawides as their competitors. They might as well just sell the iPhone with a single camera again, because the other 2 are just so far behind.
