Video: The making of a 500mm F/4L IS Canon lens

It's probably a little early in the week to start watching Youtube videos on company time, but if you have 14 minutes during your lunch break, you can witness the process involved in taking raw materials and turning them into a lens that costs just over $6,000 when finished. The videos have the same informational feel as the informational films we used to see on Mister Rogers' Neighborhood when we were kids. We love looking inside our favorite gear and, in this video, you're walked through the entire process from creating the glass from a pile of powder to the incredibly complex assembly of the familiar beige body. Next time you're thinking about how much money you spend on lenses, it might be worth bringing these up again just to be reminded why a good piece of glass comes with such a high price tag. See the next two parts after the jump.
