It does. The whole question is: what's the finest detail a device is able to deliver? Everything a photographic lens does is "tie" the incoming rays of light together and put them the correct spot on the sensor or film. While a bad lens would make two black dots with a little bit of white space between them appear as one while a better lens would deliver both dots and the spaces. The better lens RESOLVES the incoming light into a more appropriate "package" that contains more information.

It's pretty large, considering the 500mm focal length (F). Remember, it's a function: The diameter (Ø) of the aperture in a F/4 lens when the focal length is F=500mm, is: Ø=500mm/4=125mm. In comparison, the diameter (Ø) of the 85mm F/1,2 is a measly: Ø=85mm/1,2=70,83mm. For a 85mm lens to have the same diameter aperture as the 500mm F/4 (Ø=125mm), it would have to be a 85mm F/0,68 (!) Ø=85mm/0,68=125mm In other words: F/4 on a 500mm lens is huge!
That's due to the fluorite lens element and the ultra-low dispersion element - both are very expensive due to the high cost and difficulty 8n creating the fluorite lens. It's laboratory grown crystals.
This model is no longer manufactured, and the second incarnation is the one currently being produced and sold. It has an MSRP of $10,500. Mother of God.
We are talking about digital HD not Film and HD in TH-cam didn't pick up up until the the end of 2009 and back then not everyone had a fast internet speed to see HD videos so not everyone would bother to upload in HD.
2:16 I guess I'll never find out how these four most critical steps to improve the glass. I just have to take their word for it that it works. The rest I understood.
I think he meant the front element size, which divides the focal length with the maximum aperture. So the lens in this video actually has a larger front element (and therefore aperture [hole]) than my Canon 100mm f2.8. But yes, my 100mm is quicker than the 500mm mentioned in this video.
Ironically, at only 240 dpi vid resolution, it wasn't very clear... 🤔 I would have liked to see even more details re. the homoginisation & clarification processes as well as the final polishing... 🤓👍
After about 2m30s nothing of any interest was presented, "Here we made the lens glass ever so precisely and carefully, we did this and that, and there we are, aren't we clever?".
Well holy shit I am glad I was told about that. You learn something knew every day. So f/4 can be wide or small depending on the diameter of a lens? So really, it's all comparative? Thanks for telling me that! Very informative and I won't make a dick of myself in the future.
Ok, so the F-stop is simply a ratio. It doesn't matter how big a lens is, the ratio will be the same. So F4 on a lens with an 82mm front element diameter is the same as F4 on a lens with a 52mm. Its calculated by dividing the focal length by the diameter of the aperture. Its generally used as a measure of light transfer, but this is actually not 100% correct, as each lens can have various levels of that (this is actually the T-stop of the lens) even when using the same F-stop. In general though, F4 on say a 200mm lens will allow for roughly the same exposure settings as F4 on a 35mm lens. Its just the focal length relative the size of the opening of the iris; the longer a lens gets, the wider the aperture has to be to allow the same ratio. On some lenses that zoom from one FL to another, you might have what is a variable aperture, expressed like F4-5.6. This means that as you zoom the ratio can change, and your exposure will be effected. Some zooms have a constant, usually your more expensive F2.8 or even F4 lenses (70-200mm comes in both flavors). This means the ratio does not change as you zoom, as the lens is engineered to work this way, which is part of why they cost so much more than the variable lenses and usually have more limited range (a 70-300mm will almost always be variable, while most 70-200mm are constant). Sorry it took 7 years to find your comment and reply, LOL. You probably already found all this info in that time. But maybe someone else is just now finding it and still needs it. So imma leave it here.
@@rowanaustin8745 I think Canon lenses are fine, as they are from Sony, Nikon, Fuji and other Brands. At least if you are comparing lenses on equivalent price levels. I was just joking which is indicated by the smily. ;) The perfect lens and perfect sharpness is not so important to a good picture in my opinion.

1:34 Is that part of the production room open to the outside?
The 500mm f/4 IS II USM has 16 lens elements according to Canon's website.
It's pretty large, considering the 500mm focal length (F). Remember, it's a function: The diameter (Ø) of the aperture in a F/4 lens when the focal length is F=500mm, is: Ø=500mm/4=125mm.

In other words: F/4 on a 500mm lens is huge!
I always thought they were made by sorcery and witchcraft. This confirms it.
Stunning three videos.
When was this video made? And no, I'm not asking about when it was uploaded to TH-cam.
Much respect, now I realize why they are so expensive.
makes me choose a canon L over every other lense!!
Innappropriate music kicks in at 0:50 ... When the beat drops....
