The Discovery channel is using the Sony a7S to capture footage that couldn’t be obtained before, without additional lighting, which allows documentary film makers to capture sharks and seals in a more natural/undisturbed environment.
“The camera’s capabilities allowed us to shoot things we’d only dreamed about previously. When life-and-death struggles are going on between shark and seal, the last thing you want to do as a filmmaker is shine a light on the battle and influence the outcome. The α7S allowed us to be completely non-intrusive as filmmakers because we didn’t need lights. As Chris Fallows put it so well in the film, it allowed us to be “invisible spectators” into the nightlife of the great white.”
