iPhone Camera Zoom

I was standing on Imperial Hill on Wednesday waiting to pick up Leon; he was coming in from Munich on a Lufthansa flight. I didn't have my real camera so I had to use my iPhone.

Using Camera+ app, here is 1.0x (no zoom):

The A340 is the big white plane in the center. The EXIF data says 3.85mm (wide!) at f/2.8. I then zoomed in all the way (6.0x) and here's the result:

Weird. It almost looks like I added a film grain effect. The EXIF data is the same as above so it's definitely a digital zoom; there are no moving parts in the lens assembly.

Photo of approximately the same area using my Sony A55 (240mm at f/6.3).
