How camera lenses are made

Considering all the hours invested in the manufacture of each lens (irrespective of marque), the price one pays for each optic is more than justified; I cannot remember a time when I griped about the cost of any of my lenses, tho' it is understood the process for build has been largely automated - the final checks, I imagine, are all now done by computers. Fascinating insight into optical construction.

Ya I don't know how they make money with that?

thanks

As fascinating as this is. Ill never be mad about paying the price for a lens again. The engineering is just beautiful. But I bet these people still make 15 an hour. 🥲

Amazing amount of man hours goes into these lenses. This video is 16 years old as I'm watching it. I wonder how much more automated the process is now in 2023? Thanks for posting this vid!

Why does the theme actually go pretty hard

I just bought a Sony 24-70 2.8 GM II for £2099... I left the store thinking, that was fairly expensive but now it all makes sense. Fantastic lens by the way.

There's an oversimplification here. Coatings are not just for protection. They serve a purpose in how the light is transmitted through them.

Hello everyone after 16 years of wondering why these lens are so expensive

oldest video that has randomly popped up, 16 years is WILD

Why arent these people covered in lint free clothing? Even flakes of dead skin can lower the quality. These must be cheap lenses.

stupid music annoying and distracting

الفيديو قبل 15سنه🤐😮

$2,000 for a good camera doesn't seem all that expansive now.

I wont be complaining why lenses cost so much

Russians can't produce this and scramble parts from foreign products for their military drones lmao XD

If you need a microscope (which contains a lens) to makes lenses, how was the first lens made?

Great Lens making Video, thanks for sharing

Why aren’t they in a clean room?

No, it's not in my recommendation, i searched for it

2021 :>

super film and musik!!! :))))

Wanna see how the modern lens are made

Beat in the beginning go hard🔥

Music very annoying

The script was clearly written by a dad.. with the amount of puns

What causes different colored flares?

2018!?

What do they use to clean the lenses?

Does anybody know,,,,,, which company produces or assembles this TV camera?? Also, who can be suppliers of this product for this company?? Thank you in advance.

damn that's a hot beat

who is watching on 2016

I'm addicted to the music in the first portion.

This fucking music in the first half.

Seems pretty old school. I hope they upgraded their process.

6 week 1 lenses? 

what the serious fuck?! you can't automatically engrave letters?

Now I understand why lenses are so dam expensive..

damn dude, clean your fingernails.

thank you very interesting

Lot of patience and attention is required for this procedure........

I don't want to see this. I DEMAND TO SEE HOW A LEICA ASPHERICAL LENS IS GROUND AND POLISHED!

The fluorite element for the Canon 1200mm telephoto lens takes a whole year to grow.

To everyone who keeps weeping about it taking 6 weeks for a lens. Get it. They are producing LARGE VOLUMES/TIME UNIT! ! ! And besides, it is obvious that some areas are open for improvment, but that they don't show it. Like the the time they put into cleaning the lenses. Making the entire operation in a dust-free zone (like the electronics factories) would save many work-hours, just by that alone! But still, one got to give them respect. after all, lenses got to be crystal clear.

I'm pretty certain this is the time taken for raw materials to be processed into a lens. It's not just one lens at a time; they're doing this in giant batches making thousands of lenses at a time.

yea true.....no wonder why they so damn expensive

That's the type of pretentious thinking Canon relies on to sell their overpriced mediocre L lenses.

Don't be so gullible. Canon doesn't make their lenses that way. That's why a good kitlens with image stabilizer costs 100$. The Canon L lenses (where L stands for loser) is just to milk the pro sheep who foolishly pay big money for an ego booster.
