This video has been around for a while, and I think it might have been posted here before. It shows you how lenses are made from beginning to end:

However, I just came across a set of 3 videos that show how Canon lenses are made. I hadn't seen this before. Pretty neat.

Neat videos.. really enjoyed it.

 

Cool!

 

so who's ready to put together a DIY?

 

ahhh nice. I've seen short segments of how lenses are made, but these were really informative.

 

Ah thanks for bumping it... I had been wanting to see this but forgot about it!

Interesting videos. I'd like to see how they make smaller lenses and maybe go into detail of how IS/VR and AF work within the lens.
