A Guardian photographer, accustomed to lugging around huge lenses, is capturing the London Olympics with, basically, his phone -- and the images are impressive, if not incredible.
Dan Chung is photographing the games with an iPhone, an app and some after-market lenses or binoculars (but only occasionally).
Compare that gear with an 800mm lens (among others), other camera bodies, filters and backup batteries and memory cards.
Traveling light never shot so well.
