How Canon Lenses Are Made

I found this in the Photographer's Tech Resources Group.

There are good views in the "how lenses are made sections", though the types of lenses section and the interviews section are also really informative.

Neat stuff, and I feel a bit better about selling organs for lenses now :)

Argh.

That's an hour of my life I shall never get back! ;-) Thanks @_mpd_.

Seriously it was fascinating, but no thanks to that voice over guy who had the uncanny ability to make lens construction seem ten times more boring than it actually is....

Interesting they chose the EF500mm f/4L IS USM to demonstrate.

Maybe they need to shift a few more of these babies?

Yeah, he was obviously under instruction to speak the name of the lens very slowly and clearly, and many times!

Yeah, kinda reminds me of Ben Stein as the History Professor in the "Wonder Years".

Today class we will learn about....

For some reason I feel subliminally inclined to by a EF 500 f/4L IS USM ...

Very interesting video.

I prefer the monotone narrator. It goes with the video. I think I would have been annoyed it they dubbed in some slick, rock n roll, marketing type guy "Heeeeeeeeey guuuuuuys, we're making lenses OUTSIDE of the box! Yeaaah!"

The full name of the 500 f/4 should never be spoken out loud.

Wow. I knew it took precision to make those lenses, but that was way more than I expected. It's artwork in itself.

The very intresting and intense process of lens making makes me wonder how hard it must be to find and handpick those ppl and train them for such duties !!

If you spend any time in Japan you quickly become aware that the Japanese take concepts like detail, precision and quality to a whole other level - and that's not simply in manufacturing, it's everywhere in their lives, even in the most innocuous details.

For instance, if you eat in even the most basic of Japanese restaurants, you'll notice that even the little wooden toothpicks on the tables have little notched ends, about 5mm long, that you can break off so that when you put the toothpick down, you can rest the toothpick on the little stub so the toothpick doesn't touch the surface of the table. In Japan, there's no question, it's all in the details and this is right at the heart of the culture.

I have to say, I agree with the poster in one of the nearby lens threads who said that when they see people claiming thay got a 'bad' lens - particularly an L-Series, odds are that it's user error that's causing the problem rather than a defect in the lens itself.

I've used L-Series lenses for ten years and I've never found them to be anything but remarkable.
