Don't try this at home. But if you do, be sure to get it on video
DSLRs are massively complicated on the inside. So, watching this Nikon Professional Services tech strip down Nikon's flagship D4 DSLR and build it back up in less time than it would take to watch an episode of Seinfeld is really impressive.
The video is meant to show how good the NPS techs are at what they do and the time lapse effect is fairly hypnotizing. If anything, it's a nice reminder of just how complicated these machines we love really are on the inside.
