In early September, we saw a photo of sushi that was believed to have been taken with a next-generation iPhone. The photo appeared in the Flickr stream of a known Apple employee and was found to have some unusual characteristics:
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 2235x2291 (5.12 megapixels), the original picture was a much larger 3264x2448 -- 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.

With the announcement of the iPhone 4S and release of full resolution photos from the device, we see that the specifications line up nicely:

- Image size : 3264 x 2448
- Aperture : F2.4
- Focal length : 4.3 mm (35 mm equivalent: 35.0 mm)

So, it seems that this was an early iPhone 4S shot from back in July.

Well that clears up that little mystery.
 
That's why there were no leaks of the new iPhone for such a long time. It's just the same.:(

Thank goodness this finally puts the contentious sushi question to rest.
 
This photo, like the other 4S photos has a very limited set of colors (you can see it on calibrated high quality displays). This is not necessary, because the JPEG algorithm works well will color rich areas. So, if it is not JPEG, it is very likely the result of some postprocessing stage within the iPhone. Some < 400 US$ Canon cams have the same problems. It should be possible for Apple to disable the postprocessing within the iPhone 4S. Or some third party app does it in the future.

There were all kinds of leaks—even component photos—pointing to the 4S we got, which is huge upgrade over the iPhone 4 :)

All of which has little to do with the business at hand: sushi rumors!
 
Optics!

Re: earlier comment - megapixels are not the important number here - the aperture is the important number in a small camera like this. Optics and a wide aperture (which will let in a ton of light) will beat megapixels every time, especially with a small camera/sensor situation here. Megapixels are basically the digital camera industry's way to make an objective, easy to understand number by which to compare cameras. But compare a good 4 megapixel camera with a crappy 12 megapixel camera. The optics will matter more every time.

I agree - with such small sensors the lens is everything. Diffraction limits hit *early* compared to 35mm stuff. I'm sure that the iPhone 4S is diffraction limited at f/2.4 already.

*But* wider apertures have increased aberrations. f/2.4-2.8 is a sweet spot for simple high-performance lens design.

Not as huge a upgrade as you make it sound like.
 
The big deal about it being 8MP is that it's likely to have Samsung's new backside illumination, which is is said (by Samsung) to be much better in low light conditions. The sensor does matter a lot, just not the number of megapixels.

This. I hate people citing megapixels as the only spec that matters. Megapixels mean nothing about image quality in my book.
 
I think Cook missed an opportunity for a good laugh. When he was showing gorgeous pictures the 4Gs could take, he should have flashed this photo as well. The crowd would have loved it.

I don't see why he would get fired ... it's not like he let the phone at the sushi restaurant.

He was not even at a restaurant, but eating lunch at the cafeteria on the Apple campus. I'm sure he was not fired.
