The camera has been radically redesigned, incorporating a sapphire lens and better low-light capture.
It also features an 8-megapixel sensor, a backside illumination, hybrid IR filter, a five-element lens and an f/2.4 aperture. Also, thanks to the A6 processor, it is faster than ever.
The front-facing FaceTime camera has also been upgraded to 1080p HD and features face detection and the ability to take photos while taking video.
