Canon Lens Production 2

Making of Canon L Series 500mm F4L IS USM. Part 2 of 3 in the production of expensive camera gear. L series is Canon's Premium lens line featuring fluorite lenses. IS refers to Image Stabilzation build into the lens, and USM refers to Ultrasonic Motor drive that makes focusing faster than older systems. Currently I'm using a Rebel XT, although I'm thinking of upgrading to an XTi or 5DMk2. This 500 with the New 5D would be a sweet combination.

The factory that makes the forbidden skimming stones

[@AparnaMandal-h5s]

After decades and centuries of trial and error humans reached this far.

[@daradidam]

by hand grinding, therefore it was very expensive even for a single piece of lens (eyeglasses for example)

[@Randolph_]

0:41 mmm... delicious... mint candies!

[@Lostinafreezer]

Its amazing they are as cheap as they are...

[@A_Clark]

Those lenses aren't the only thing that lost focus.

[@annaandprince12]

where are the lenses made though?

[@kevinmsft]

EF 500mm is about 10 grand....

[@martinisbutik]

"ultrasonic washing machine", wait what?

[@KyleFalconer1]

[@isaacsatzman5610]

Me: NOOOO don’t f*ck up the lens Also me: remembers that they’re preprogrammed robots

[@vincentpeterpeter2516]

amazing

[@crawford323]

So many wonder lenses which are not designed to be used with digital sensors are being discarded. It seems such lens, with its pure glass could be recycled. Such a shame to toss Leica, Zeiss, Pentax 6x7 and other fine glass because technology has abandoned them.

[@fleursdelilas9487]

most of them are still usable. they just need a mount adaptor. You won't have autofocus, but they still worth it

[@ycaroovoador7744]

👍👍👍👍👍

Narrator -- Canadian? Midwestern? Canadian, I feel like.

The last step is also called vacuum deposition. This is not to be confused with when the lawyers tried to depose Trump, all they got is nothing in which all the effort and labor are wasted.

ریزه کاری

[@Jooligan1]

Canon is known for it's pin sharp resolution lenses so it's ironic we're watching an appalling resolution upload !!!

[@Ilovecruise]

This video is decade old, what do you expect?

[@chrisalister2297]

And the channel is not Canon. Geez

[@WyattOShea]

@@Ilovecruise I mean I've watched tv shows and movies from 70+ years ago with better resolution and sharpness lol.

[@Billium632]

If you're gonna rip this off a another channel, at least rip off a high quality version...
