The new iPhone retains the 8-megapixel iSight camera and its f/2.4 aperture. But it offers better low-light performance, 40% faster photo capture, more precise lens alignment and a highly durable sapphire lens cover. Overall, the unit is 25% smaller. Apple also improved the camera's image stabilization, to minimize blurring.
The front-facing camera now supports 720p high definition for higher quality Facetime video chats.
