WHY - Nikon D4 Release Video from Corey Rich on Vimeo.

An interesting look into why "extreme" athletes are so deeply connected to their respective sports, with kayaker Dane Jackson, mountain biker Rebecca Rusch, and climber Alex Honnold. In the climbing segments, Honnold solos Equinox (5.12c/d) in Joshua Tree National Park, California. This is likely his third hardest solo, the others being Heaven (5.12d) and Cosmic Debris (5.13a) in Yosemite.
