[penuli5]

[vnt87]

Fusing --> Mixing -->Clarification -->Homogenization

The process of coming out

[CandyHam]

for those who didnt catch it:

This is how the Canon EF 500mm f/4L IS USM is made

It is one of their best lenses available.

It costs between $7,000 and $11,000 at retail.

Watch carefully.

DAT GLASS

[bolderiks]

Two things:

- Were are the Jap girls?

- Nothing compares to Zeiss.

[Spectacular66]

Forged by flame!

[NLS87]

Nikkors are better

[rorrt]

It sounds like someones taken a RAVE, to a lens factory...

[TheShawMaestro]

One more thing that would be even more a wesome narrated by Morgan Freeman.

[tosykosyhaha]

the liquid glass is is shaped into a shit

[TechCuber]

that glass like weed

[twkVids]

this makes me want to take better care of my lens...

[Kentaronizer]

And this, everyone, is why lenses are so expensive!

[fleetingdays]

Very informative! I hope to purchase more Canon lens!

[MustNotRead]

"allowed to cool naturally" with a 20000KW fan blowing over it.

[tosykosyhaha]

@MustNotRead yes it makes sense.

[zeradiddle]

Notice the how the letters and numbers on the electric furnaces at 6:00 are not Japanese...

[principle001]

i'd like to see how the 50mm 1.8 is made

[NLS87]

@principle001 in a sweatshop... somewhere in china, or worse... LOL!

[RickyJ46]

A surprising amount of hand finishing is still required, the tradition of old world craftsmanship continues.

[arroy624]

4:26.... how???

[onjoFilms]

The glass is set upon a hot rod/knife that acts like a glass cutter that breaks the surface tension. It then can be broke apart by just pressing or bending.

[SuperMediocre]

If I were a japanese i would have worked for canon(i mean in the factory..)!!! soooooooo cooooooooolllllll

[francio22]

how can we know that those lens are canon?

[Pace189]

The lenses are Canon because the lens referred to in the video is 'EF 500mm F4 L IS USM' - EF being a Canon lens mount and USM being a Canon focusing system. :)

L is also Canon's pro range of luxury lenses.

[d4n131M3j14]

The thing is that the workers don't seem like they win more money than the ones working in other low precision factories.. I thought they should win more with all that "hand-made" crap.

[PiNKGstring321]

no wonder they are so extremely expensive

[PiNKGstring321]

agree very hot in there, 0.56 - 1.08 jees hes /shes stirring it with bare hands above the hot stuff.

[ryman1]

I like how the inspector dude checks the glass for defects through his smeary 3 dollar plastic safety glasses.

[kweechy]

@ryman1

He's a skilled Japanese worker. He'd be able to sense glass defects even blindfolded, Jedi style.

[chadsexinton]

i wanna drink a hot cup of glass.

[Foreezybeezy1]

Same

[korgri]

THEY MAKE LENSES OUT OF COCAINE??!! I guess that helps the pictures look so sharp-n-snappy..

[glydeuserhelp]

lmao to bad u can snort the lens

[vitacit]

how many factories for lenses production has canon all around the world ?

[lawbra]

Must get real hot in that factory.

Lol

[john21031]

The $7,000+ for the lense is still not justified by this process. Look at it, it's crude, it's like a brick making plant, they produce thousands of these lense.

The price must be inflated through the marketing manipulations....

[humanpower]

I'm sure you're right, John. Why, I bet you could make one for cheaper in your garage.

[indigophox]

Yeah. I love how many little bits of rocks and crap there are in my fluorite Canon front elements. Looks just like a brick. Maybe I'll see if I can get an adapter, and just USE a brick, although I guess I'll have to use manual focus. But hey, I'll have something like $6999.50 instead of autofocus, and the same optical quality!

For that matter, have you seen the processes used in making CPU dies, some of which go for >$2000 for a little tiny chip? Psh.

[theidiot321]

Post your trash somewhere else

[blp0]

Stop degrading youtube.

[dinosoarskill17]

WOW
