Quality in Photographic Lenses : Lens manufacturing

Hello Friends,
This is not a video of mine but it reminds me of my time working in optical manufacturing. Yes, even if the video is from 40 or 50 years ago, all of what's shown it is still true today.
Found the video in really ugly format somewhere on the net a long time ago, I upgraded it using one of those AI softwares for video, results are not perfect but lot better than the initial video.

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.

So this is what happens when you crank up the AI restoration to max :D

[@diyextravaganza]

Sadly the quality was extremely bad and after trying different algorithms, all results looked pretty much as this one. Cheers.

[@JanneRanta]

@@diyextravaganza Great film still. Do you have more of these?

[@diyextravaganza]

@@JanneRanta I don't, found this one a few years ago and kept it preciously. With the appearance of AI video improvement told myself it was time to share. Cheers.

[@JanneRanta]

@@diyextravaganza Shame. These kinds of videos are super interesting. Would love to see one like this about camera bodies too.

[@diyextravaganza]

@@JanneRanta Sadly documentaries like this have become the exception, I remember as a kid watching things like this all the time in the long gone educational channels. I saw this recently on a German channel which have excellent content (but everything is in German). www.br.de/alphalernen/faecher/physik/physik-einfach-erklaert100.html

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.

[@diyextravaganza]

Thanks a lot my Friend.

[@jph364]

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

[@diyextravaganza]

@@jph364 you're most probably right given the clothing and haircuts.

[@oc2phish07]

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.

[@diyextravaganza]

Hi thanks, I worked in optics and one of the first things they told me was: things haven't changed much in 100years ( when talking about the general manufacturing) cheers.

[@sasquatchentertainment3568]

Love the old Warner Brothers-esque cartoon music

[@diyextravaganza]

@@sasquatchentertainment3568 totally agree with you. Best

[@javier7high]

Beautiful video. Thank you very much for sharing!

[@diyextravaganza]

You're welcome my friend. Cheers.

[@cameradoctor205]

Love the letter to the design dept 😊

[@diyextravaganza]

other times :)

[@agxiso]

thank you

[@diyextravaganza]

You're welcome.

[@TheEPROM9]

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]

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.

[@martinmuldoon603]

​@@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.

[@jfess1911]

Thank you.

[@diyextravaganza]

You're welcome my friend. ,😊

[@03chrisv]

I wasn't expecting their "calculator" to be the size of a room lol. What took weeks can be done on a smartphone in seconds. Crazy.

[@diyextravaganza]

Lol, yep. And yet, they were able to produce great things. Best

[@patrickgueguin792]

Thanks

[@diyextravaganza]

You're welcome my friend

[@richardsimms251]

Great video

[@diyextravaganza]

Thanks, I've always found optical manufacturing fascinating. Cheers.

[@sippinhappiness793]

love it

[@diyextravaganza]

Happy you liked it !

[@sergeydorovskikh]

wow

[@diyextravaganza]

I said the same thing I saw this video for the first time :)

[@daledanowski9962]

i love it

[@diyextravaganza]

It's a beautiful video

[@1967CougarXR7]

I truly enjoy these old how to or how it was done movies. But to me, and this isn't the only one I feel this way about, the AI enhancement jus doesn't do it for me. It seems like AI turns a video into a bad copy of a bad copy of a bad copy....But thanks just the same.

[@diyextravaganza]

Hi, I do agree with you, the AI "enhancement" does look very artificial but the quality of this video was very poor. Thanks for following the channel. Best.

[@mr_cramberry]

It's a great shame Kodak is just a shell of what it once was

[@diyextravaganza]

it is.

[@spookisghostly4619]

I miss when Kodak made good American lenses instead of licensing out their name to cheap plastic point and shoots

[@diyextravaganza]

That's indeed a great loss and one reason I avoid buying cheap optics. Best.

[@georgedegroot8333]

What year is this wonderful flim

[@diyextravaganza]

Sometime in the beginning of the 60s, or maybe late 50s.

[@twoeggcups]

unwatchable

[@diyextravaganza]

ok

[@bikermann42]

I disagree.
