    fascinating, but rather than 40-50 years ago it feels more like 60-70 years (1950s-1960s)

    I just got around to watching this - fascinating. Wow, so much automation so long ago. And the "calculator" took only a few weeks to get a result 😃. And the Disney style dramatic music - it really is of an era.

      When I discovered the video first, it reminded me of the time when I worked in optics, many things haven't changed, the computer part yes. It also gave me a nostalgia of when I was a very small child and everyone had this spirit of investing themselves to go further and make beautiful and better things, that spirit seems long gone. Cheers.

    Very beautiful video. So many workers and technicians. Whatever happened to those beautiful machines. So many people were employed. Beautiful days in deed. Million Browny points.

    Excellent video and so very interesting. I was amazed to see how much of the main manufacture of the lenses, the molding and polishing etc. is almost exactly the same as the most modern manufacturing plants use today. Thanks for posting this, I really enjoyed it.

    Decades later people like me are restoring these lenses. They were well built enough to normally only need a good cleaning & the mechanical parts re-lubed up. So the lenses can server for more decades to come.

    • @diyextravaganza
      @diyextravaganza  Год назад +1

      This is the beauty of old lenses, they give us many emotions thru the special images they help us create, and we can keep them going indefinitely. I like some modern lenses, but I tend to steer from them as the build quality is certainly not at the same level. Cheers.

      ​@@diyextravaganzathanks for posting this great video of how Kodak manufactured great lenses years ago, it brings me back to a time when people aspired to do things well also where the general people appreciated fine precision instruments, I find our young people take everything for granted, nothing impresses them any more no matter how good, or precisely made. We now live in the iPhone, Internet generation where information, knowledge, answers to any question are just a few Google searches away, automated machines can do things over and over with even less need for human hands or intervention, soon machines will make machines to build everything we want or need therefore we have less and 24:40 less value of the people who laid down the foundational concepts of our modern world.

    I am stunned !!! how come was this possible with such an egregious human and manufacturing equipment involvement in States to make those lenses affordable for masses ! unparalleled ! I was convinced , as a movie and photography professional , that those cheap lenses were made by asians in 4th row countries literally on their laps from pieces of discarded materials . how how was it possible to charge for such a marvelous tremendous work so little . no lenses that are made in similar fashion yet still a lot faster by germans costs at 4k usd and up to 25-30k usd a pop ! all and all terrific video such an emersion into better days America . thank you ! so long @georges_angeles
