What is claimed to be a photograph taken with the iPhone 5 has been circulated online.

The Pocket Now website has published the image which it says was shot by an Apple engineer eating his lunch at work.

The EXIF data of the image, which is of a rather appetising plate of sushi, shows that the original image was taken at a resolution of 3264 x 2448 pixels, which is just under 8MP.

However, the image has been cropped to 2235 x 2291, which is just over 5MP. But the EXIF data also shows the lens to be a 4.3mm f/2.4, whereas the iPhone 4 has a 3.85 f/2.8 lens.

The ThisIsMyNext website has further analysed the image and claims that the device that took the picture can be seen in the reflection from the edge of the plate. However, it's difficult to make anything out from the image, except for a person holding a something between two outstretched hands.

8MP camera for iPhone 5 evidence strengthens

"Is this the first incredibly indistinct picture of the iPhone 5?" the site asks. We're not so sure - after all, the EXIF data could easily have been faked.
