Matthew Farrell, Michelle Pang, Michael Tom, engineering students of Engineering 128 class from University of California, produced an exploded view (and re-assembling) of a Canon EOS 10D with a 24-85mm F/3.5-4.5 lens to show how complex a digital DSLR is. The video was made 4 years ago. It is not entirely clear if they used blue-prints from Canon but I guess they did the whole modelling on their own. Kudos!
The EOS 10D was introduced February 2003. It had 6.3 MP sensor, a 7-point AF system, magnesium alloy body, ISO 100-1600 (3200), 3fps.
