When you’re trying to convince photographers that an $11,000 camera lens is a worthy investment, sometimes you need more than a list of specs. So Canon created a short stop-motion video of its EF 200-400mm f/4L IS USM lens disassembling itself and revealing all of its wonderfully complicated internal components.

If you already own the lens, this is your chance to peer inside at all of the electronics, motors, gears, and lenses that make it work. The last thing you want to do is crack it open itself. Taking it apart might be easy, but putting it all back together? Not so much.
