Well just call this guy Mr. Magic Hands because he makes dissembling and repairing one of the best cameras in the world look so easy that it must be sleight of hand. I know this is real, but I still can't believe it.
In just over 20 minutes, the Nikon Professional Services tech disassembles Nikon's top-of-the-line D4 fixes it up, and puts it back together. Yes, this is sped-up footage, which helps contribute to the video's wow-factor, but think about how fast 20 minutes is—that's the approximate run-time of a TV sitcom episode. Ludicrous.
That's nothing considering high-end professional DSLRs are notoriously difficult to take apart and put together. They contain precision guts, which are crammed into weatherproof shells that are expected to be as ergonomic and compact as possible. This is magic. [Nikon Rumors via Imaging Resource]
