"The situation: You are in the middle east and there is a huge flood in progress. Many homes have been lost, water supplies compromised and structures destroyed.
You are a photographer getting still photos for a news service, traveling alone, looking for particularly poignant scenes.
You come across Osama bin Laden who has been swept away by the floodwaters. He is barely hanging on to a tree limb and is about to go under. You can either put your camera down and save him or take a Pulitzer Prize-winning picture of him as he loses his grip on the limb.
So the question is, and consider your answer carefully:
Which lens would you use?"
