Canon is doing it right. Before anything else, before their plug is even mentioned, its just about science, & that is what we come here for. If there is that much simplicity & honesty in their products, i trust them to make a mighty fine camera.

Sir good evening , what are differences between spherical and chromatic aberration and aways of minimising.

this is insanely informative...

[@mirageleung1575]

This was brilliant... at 0:45 it clarified what other videos make confusing, in that an image is made up of an large amount of point light sources based on the resolution, in order to generate the image. Where other videos make it confusing is they generally only show one single point

[@aurelia8028]

0:45 That little animation here shows more clearly why images appear upside down than any other explanation I've either seen or heard. The best way to learn physics really is to be able to play with models, applying equations, yourself.

[@HowardPhillips]

Very nice, will definitely be sharing this with my students, On the other hand may I humbly suggest using the term 'elements' or 'lens elements' when describing the correcting elements like the convex element, that make up the overall lens itself? This is feedback from some of my students, by the way. Thanks for a clear and simple video.

The sensor is the main responsible for the creation of pictures, but the lens is the main responsible for its beauty.

[@muhammadkamrankhan6300]

Wow its worth watching this ad

[@waqasaslam7678]

I am studying Ophthamology , and i cleared my concept from here😅❤

[@anomalyp8584]

One thing...the power of a lense is expressed as the distance to its focal point. But the image (light rays of objects going through the lense) will never focus at the focal length of a lense. Right? So, is this why the sensor will not be at the focal length of the lense? And consequently why the focal length mentioned on the lense itself is only referring to its distance to the sensor?

[@l3yfajamz]

Though the light in a magnifier burns at that focus point, am I right in thinking that it technically isn’t magnifying anything at all. and that it is just concentrating many light beams to one spot, which means light isn’t increasing/ speeding up thus not magnified?. Thanks great video 👍

[@lucetto]

Why not make transparent, stacked sensors for r,g and b, that were part of a sphere? You then only have to take care of fov with the lens.

[@moseleenone7252]

Rly informative video. Is it safe to say that different lens are needed to adjust the wavelength of the different light colors to ensure that e.g. the blue and red light converge at the same point?

[@stevenmiller4329]

that is the distance between lenses

[@llllllllIIIIIIIIIII]

Its more complexe than that. Your model should be converging from both sides of the lense.

What is the convex lens isn't spherical, but a parabolic one? They focus light from the whole lens on single point, right? Wouldn't that remove the need for the corrective concave lens?

If you the property of each lens then by taking further information you can select the lens of your choice

@@thanos3661 Is there any simulator available? without playing with the real glasses? If we can test the properties

[@a2editz605]

[@helloansuman]

@@a2editz605 sorry I have no idea. I have seen in some KZbin video. There are some simulators.

[@juliusfucik4011]

@@helloansuman There are software packages for simulating lense combinations. You can even simulate your own lense elements with mirrors, light projectors and sensors using finite element methods. This sofrware is expensive and requires a decent amount of training to be able to be used effectively. You can assume there is simulation software for every process in design and production. Complete CPU designs can be designed and tested in software.

[@its.mahnoors]

Im watching it in 2022 to prepare for my test

[@IARRCSim]

How does a metasurface lens work to make clear images? Fresnel lenses aren't useful for focusing clear images because they can't focus more than the focal point. Light even a few degrees from the lens' axis create blurry streaks instead of points partly because a Fresnel lens doesn't slow light anymore near the axis than its edges. I can't see why a metasurface lens wouldn't have the same problem.
