Here is a photo that I found on Macrumors and it could be taken by the iPhone 5. According to a Report I was taken by a iPhone 4 but this picture before cropping was 8 megapixels but the iPhone 4 is only 5 megapixels so this just could be a iPhone 5 Camera.
This (very attractive) photo claims to have been taken by an iPhone 4, but the rest of its EXIF data tells a different story: although the image has been cropped to 2235×2291 (5.12 megapixels), the original picture was a much larger 3264×2448 — or just shy of eight megapixels. What’s more, the lens was recorded as a 4.3mm f/2.4, which is closer to that of a point-and-shoot than the iPhone 4’s actual 3.85mm f/2.8.
The thing that makes the rumor even bigger is that reports say a Apple Engineer took the photo.
