Convincing yourself that an $11,000 USD camera lens is a worthy investment sometimes requires more than just a list of specifications. 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 this fabulous lens, then this is your chance to peer inside at all of the electronics, motors, gears, and lenses that make it tick. The last thing you want to do is crack it open yourself. Taking it apart might be easy, but putting it all back together? Not so much….Time to get your geek on and enjoy.
