I have a moral question for you. This is an imaginary situation:
You’re in the Midwest, and there’s a huge flood. Homes have been
lost, water supplies compromised and cattle destroyed. You’re a
photographer looking for particularly poignant scenes.

You come across George W. Bush, who has been swept away by
floodwaters. He’s barely hanging on to a tree limb,he is weak and is
about to go under. You can either put down your camera and save him,
or take a Pulitzer Prize winning picture as he loses his grip.

So, here’s the question, and think carefully before you answer it:

Which lens would you use?
