@@SezerPAL It’s all of the above. This was recorded on video, had it been recorded on film they could easily reformat it and release it in 4k today. This is how most properly “remastered” or reformatted movies exist. If recorded to film, at least common 16mm or 35mm stocks, there’s plenty resolution to scan them at full HD or QHD, but if recorded to video at NTSC or PAL, it sort of is what it is.

Means the lens is also centered. If you spin it on its axis there is no motion on the projected image. Projected on the film plane. Ultimate optical test.
expensive but worth it. give a thought to the precision of every component, not even counting the glass. and consider what went into the design in the first place, damned impressive
This lens has an EF mount, 500mm focal length, f4 aperture, L-Series, Image Stabilization and Ultrasonic Motor. Only $9,000 US little to no chromatic aberration, smooth bokeh and sharp wide-open.

4:57 I would never would have guessed that some of the large lenses (or any lens really) were primarily formed into its relative shape with a press. I know it only creates the rough shape, but I would have thought that pressed glass would introduce microscopic fractures or at least do something optically unstable. I guess it clearly helps that the glass is already in a perfectly homogenized state, or for sure you end up seeing artifacts after pressing the glass.
*_CANON makes World Class cameras and lenses..._* I have used Canon exclusively for the last 2 decades. While I can't say I own this remarkable lens in video, I do have other Canon lenses.

I was paying attention to that. I worked at a studio where we produced technical product videos. The owner did most of the voice overs. The calmness and patience to speak repeatedly, including saying a long boring model number over and over is something to witness. It sounds like a lame boring job but the good ones really stand out, by not standing out.
@@EVRLYNMediaseems that you’re just too young, this video has been recorded at the early 2000s do you expect 4K super sharp images out of a video recorded 20 years ago?
@@RobertLeeAtYT Seems more like early 2000's. This lens came out in 1999 and the music is very much not 90's but has that distinct "how it's made" kinda quality to it.
In the molten liquid, the different materials separate depending on specific weight. The lighter contamination floats on the top as slag and probably is removed before casting. Heavier contaminations go down, of course. But as you saw in the video, every step is quality-checked after the operation.
Exactly! I grew up with this quality and people these days are too used to everything being super high res. Sensor and codec technology has improved so much over the last 20 years.
Yeah, if only he repeated that they were making a 500mm EF L IS USM lens a few times through the film, that would’ve really added to the documentary. 😅😅
Because they want you to buy it. They want to imprint in your mint the "Canon EF 500 f4 IS USM". It is not a documentary video, it's an advertising one 😀 I will go to buy one!!! 🙃
Who gives a rats? Maybe your next video about the lens production process will have a much better script. Let me know when it's been produced so I can critique it.

You don't want lens to fall apart by itself while you shooting at football pitch or safari or wherever... Securing retention rings with glue is standard practice in lens manufacturing, and in need of service glue can be dissolved with IPA or acetone.
I don't know how old this video is but I find it pretty funny that a video about high quality optics has such a low resolution.
How are they supposed to film with the high quality lens when they haven't finished assembling it? 😀
Use the prototype
I’d guess early 1990s. The video resolution sucks, but there are several shots that suggest the camera(s) actually use a pretty impressive lens.
maybe resolution is not about lens but sensor?

Not worth the money, you can get a new lens with way more reach and over-all better IQ with less money.
I can buy a wife for far less than that.

Would be nice to see a new video with the RF1200 mm f8 IS L USM
Well only the assembly is different, so what would be more interesting would be a cutout of the lens I think.

They didn't coat the entire ring with adhesive, I imagine you could remove it with a heat gun.
