    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

    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.
