Sadly, that's all gone now.
quite amazing thanks for posting the link
would be interesting to see & compare the modern methods
Modern lens manufacture is not significantly different. It's a bit less labour-intensive but lens.grinding is lens-grinding.
I seem to remember seeing more modern Zeiss or maybe Leica lens videos on youtube if you want to have a search and compare
i was thinking they would be more cast to shape
there's a big section in the RPO film devoted to how the individual lenses are moulded (cast).
Almost every lens element ever is moulded to begin with.
That is excellent - thanks for posting the link.
