Walking Across a Full MoonBy Norman Chan "Dean Potter walks a highline at Cathedral Peak as the sun sets and the moon rises. Shot from over 1 mile away with a Canon 800mm and 2X by Mikey Schaefer. This shot was part of a bigger project for National Geographic called The Man Who Can Fly." Incredible video shot using a telephoto lens. At 800mm, the Canon lens they shot with is the equivalent of a 32x optical zoom. The lens alone also retails for $13,000. The gravitas required for the stunt is priceless.
