Enjoyed. No wonder they cost what they do.
I have watched it previously in YouTube. The design of a lens goes to optical engineers and computers the rest, as you saw is mostly done with machines till the final assembly. The video does not show the different types of glass that are used in the manufacturing process of a lens. LD and rare earths glass are used extensively today by all manufacturers. The same technology is shared by all independent companies. Quality control and precision manufacturing is what separates the good from the mediocre lens. Even in cheap kit lenses you can find good optics today.
Thanks for posting - just fascinating to watch!
Yes, that is an interesting process. There are several online.
A few years baxk someone posted the formula from Leica
that made their round lenses focus on flat sensors so good.
Big long equation thing.
I don't miss fuzzy corners, neither!
