Unlike the previous models, the rear-facing camera is not flush with the rear of the device, but instead protrudes slightly. Still photos can be captured during video recording. Those have a resolution of four megapixels (2720×1532). The camera also includes phase detection autofocus. The iPhone 6 Plus camera is nearly identical, but also includes optical image stabilization.
