FYI, I am still a full time working shooter, I just teach one day a week to give back / mentor.
The image quality on these phones is excellent in most ways organically, the new phone easily handles magazine spreads.
But this new portrait feature is still work in progress, hence Apple's likely hesitation in releasing it. In almost every image I made with it, parts of things simply disappeared from the object they were connected to instead of rolling off out of focus or being in less focus without the feature.
Simply put, photos not using the portrait software looked far more natural and real. I'm not looking for the out of focus rendering of a Leica 50mm 1.4 aspheric lens but I am also not accepting of what looks like a botched photoshop job, even from a phone. And no skin off my back, I always have at least a Leica or a Rolleiflex with me anyway, I am never without a real camera.
Maybe in the future it will do better.
