Apple’s iPhone 12 Pro heaps improvements on the already-formidable power of its camera system, adding features that will be prized by “serious” photographers — that is to say, the type who like to really mess around with their shots after the fact. Of course the upgrades will also be noticeable for us “fire and forget” shooters as well.

The most tangible change is the redesign of two of the three lens systems on the rear camera assembly. The Pro Max comes with a new, deeper telephoto camera: a 65 mm-equivalent rather than the 52 mm found on previous phones. This closer optical zoom will be prized by many; after all, 52 mm is still quite wide for portrait shots.
