The iPhone 5s improved upon the iPhone 5's camera in many ways. In our own camera comparison, I found that the iPhone 5s performed exceptionally well, especially when it came balancing colors and exposure. This was extremely evident in panorama comparisons. If you're still wanting more image samples, the guys over at Austin Mann have an amazing review of the iPhone 5s' camera posted. Not only do they have lots of sample images, they went straight to Patagonia to get them.
