Well, well, well! Look at what we may or may not have here. Internet conjecture tells us that this is the first photo leaked from the iPhone 5's camera.
Close examination of the photo's EXIF data gives away a few vital clues. First, the aperture is f/2.4, which is a tad faster than the iPhone 4's f/2.8 lens. Secondly, the photo has been cropped from an original source image of approximately 8 megapixels (3264x2448), when we all know that the iPhone 4's camera is only rated at 5 megapixels. Finally, the geolocation data in the original image (since removed from Flickr where it was first found) plots the photo as being taken in Cupertino, California.
Ring any bells yet? Apple's canteen serves up some pretty nice-looking food, if this photo is to be believed. If you would like to inspect the photo for yourselves and do some EXIF investigation, you can find the original image here, courtesy of tech blog Pocket Now.
Inspecting the image at 100 per cent magnification shows some interesting clues, as well. The noise profile of the photo, reported to be taken at ISO 64, which is a very low sensitivity, looks remarkably like the noise profile of photos taken on the iPhone 4. The focal length of the lens is, according to the EXIF data, 4.3mm, which makes it less wide than the iPhone 4's lens. Without knowing the physical size of the sensor, we can't yet estimate the approximate 35mm equivalent of this mystery lens.
EXIF data can definitely be faked or altered, so, as per usual, it's always wise to take something like this with a grain of salt. However, to stoke the flames even further, someone over at This is My Next has even enhanced the original image to show the reflection of the person taking this photo.
