Some people have already gotten their hands on the iPhone 5S. They're saying there's one thing that makes it better than the iPhone 5C; the camera. The new iSight camera features a bigger aperture (F/2.2), more megapixels, and what Apple is calling "True Tone" flash which offers two LED lights giving 1,000 flash combinations in an attempt to balance the light of a given scene. It also has a new burst mode that can capture 10 FPS.
Cameras are becoming a top priority among smartphone users as it's usually the only camera they have. Apple has listened and looks like they've delivered a much better product. It'll be interesting to get my hands on one and see what it camera can do.
