I ordered an iPhone 15 Pro Max (and another one for my wife) but even though I like the 5X lens and will probably use it, and I really like having more battery and a bigger screen, I feel like it's a huge compromise that's going to let down the whole experience. The reasons are that a) testing has shown the Pro Max photos to be of MUCH worse quality than the Pro between 3X and 5X, which is the most common focal lengths you'd want for portraits, and b) the 5X lens only has a 12 MP sensor.
To really do this right, I'd want to see 4 lenses: a 0.5X, a 1X, a 3X, and a 5X/6X, and all with full 48 MP sensors. But I doubt they will do that anytime soon.
I hope I don't regret buying these for nearly $3K.
