Revisit the physics of how lenses work, and how refraction, spherical aberration, and chromatic aberration come about. Have more questions about lenses? Check out our lens FAQ here: goo.gl/2VGQAk
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.
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.
I'm studying for an exam and I'm referring to this. This one is so much simpler and more accurate that what the RU-vidr teach. Amazing ad!! They definitely know how to market these babies.
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
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.
As a full time fuji shooter, i see people bashing canon and they write cannon, just fool yourself. This was very educational and apply's to all brands! Thank you canon!
Honestly, I just landed here's because of the science interest. If I ever have an interest in cameras or photography, rest assured, I will choose cannon now lol. Thanks for the direct, uncut information, before even knowing this was a cannon channel.
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 👍
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?
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?
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?
@@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.
