It comes with some verrrry powerful cameras
As you've likely heard by now, the iPhone 7 Plus's dual-lens camera setup is a game-changer, giving you the power to take higher quality zoomed-in photos, shift an image's focus after you've taken it, and take much better pictures at night and in low lighting.
The single-lensed 7's 12-megapixel camera is a big step up, too. It's equipped with a fresh new image stabilization feature to compensate for your shaky hands, and a True Tone flash that's not only twice as bright as the the 6S's, but has a sensor that detects flickering in surrounding lights and compensates for them. For you selfie fiends, you'll also be happy to know that the quality of the front-facing camera in both the 7 and 7 Plus has been seriously improved, going from five to seven megapixels.
