Mmmhh Sushi: this could be the first picture taken using an iPhone 5 handset  that was identified using EXIF data associated with the image itself.

The HD picture was spotted by the guys at PocketNow and they say that the ‘test photo’ data associated with the picture identified the device as an iPhone 4…but the rest of the specs are saying otherwise.

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. (Remember that the upcoming HTC Runnymede is said to have an aperture of f/2.2.)

The picture was cropped down to 5MP but originally was 8MP in resolution. The lens used was recorded as 4.3mm f/2.4 which is different to the iPhone 4 3.85mm f/2.8 lens.

How do they know the picture belongs to an iPhone 5? The data contained in the photo’s EXIF is geographically locating the sushi plate in one of the buildings of Apple‘s headquarter.
