Interesting stuff, a lot of effort for a few beer glass bottoms, mind you I've seen some wondrous things through the bottom of a beer glass.

yes indeed, wonder why there isn't any dust that get into the lens in that kind of environment.. :shrug:

Thanks. Have seen it before, but good to watch again... Especially the narrators long and overworked pronounciation of

E-F 500 F-4 I-S U-S-M lens

That is an excellent video, always wondered how they made a lens.

Actually surprised they don't wear hair nets or work in dust-free environments but that's obviously not an issue.

Thanks for posting Shamus, very interesting, I had no idea. Also helps to explain why they cost so much.
