Guardian photographer Dan Chung, like so many photojournalists right now, is at the Olympic games in London. And like his fellow photographers, Chung is doing his best to capture the emotion, athleticism, and drama of the games. But for Chung, there is one notable difference: he’s doing it all on an iPhone.

Armed with just an iPhone 4S and a pair of Canon binoculars (with post-processing done in iOS app Snapseed), Chung has managed to capture some great shots. They’re certainly different from the usual ideal of sports photography—much of the fastest action ends up blurry—but they have a look all their own that offers, quite literally, a new lens on the Olympics.
