Very nice
if you are interested in the assembly process (rather than lens optics manufacturing) skip to part 3
thanks for sharing

Pretty neat!

Great videos. I really enjoyed seeing the glass being made into lenses.

Yeah, I thought it was pretty entertaining too, plus it blew me away, I always wanted to know how they did lenses, but I had no idea is was so archaic in places, and high tech in others.

I kind'a see now why they charge so much... Kind'a...

Nice! Thanks for pointing this video out!

man, a stove and an oven I can damn near re-create that!

Love it! They showed this at my photography club about 4 months ago.
Kind of helps you to understand, how some lenses can be sharper than others.
