Juan,

Thanks for that, it was interesting. The first comment is right. There's got to be an easier way, surely?

That was interesting. Thanks.
I keep trying to juxtapose an army of Japanese women manipulating abacuses with this process and keep failing.

Not really. This seems to be JML, one of the last US lens makers, and a specialist for custom and small series lens production, so that they have a unusual amount of manual processes. In modern mass production, many of the stages shown there are automatized - but apart from that, they do just about the same.

I was a bit surprised at that mix of lots of machinery and lots of human control... Not easy making lenses... And designing new ones must be tough too!

Cheers,

Juan

Not that much differnet than small / medium series in mechanic

I'd love to see this process in the Cosina facility ... partiularly the Zeiss lenses.

Thanks for the link Juan ... that was fascinating.

 

[Juan Valdenebro]

I'm glad you liked it, Keith... I enjoyed it too... It's very basic, but the only general view I've seen...

Cheers,

Juan

Fascinating Juan, always interesting to see videos about lenses and cameras.

I'm never going to complain about a len's cost ever again. (except for the ƒ.95 noct 😛 )

Wow- 6 weeks to make one lens. no wonder I have to spend all my lunch money to buy them. 🙂

Cool. Thanks for posting this.

and then people like us forum dwellers pick them apart for every little imperfection. 😀

Thanks for the link. Great video.
Old world craftsmanship with new tech methods.

And to think lenses used to be ground by hand. It's good to see that somethings are still made the old fashioned way.
Hard work with attention to detail. 🙂

Did you notice the tech using acetone to clean the lens after it was coated?

Could some expert shed a light on how those high power (100X), APO grade microscope objectives were made? I am always intrigued how those tiny elements were polished and assembled?:bang:
