When you think of professional photographers shooting sporting events, you usually visualize huge Canon or Nikon lenses mounted on expensive camera bodies on top of massive tripods. But as The Guardian's photographer Dan Chung proves, sometimes you can do just as much with a lot less. Throughout the Olympics Chung is photographing the games using only an iPhone, an app, and (occasionally) an add-on iPhone lens or some binoculars.
The stunning image of Michael Phelps shown here was captured by Chung using only the iPhone 4S with its 8 megapixel camera and the excellent iOS photo editor
