I never saw any photography video on RUclips could explain so much information in such simple clear efficient way with such fantastic stunning animation! Thank you!
@@ApalapseI’m very grateful as well. The information is delivered so efficiently I had to pause several times and go back. There’s no fluff, I love it!
Continuing what I've said in the Aperture video... DUDE: on 0:34 can you please explain how is that nobody use such clear and obvious image to explain the angle of view? You just rock, man.
I've looked all over for this answer. Every video promises to "explain" camera lenses, but NONE of them explain exactly what the numbers mean - except this one. I'm not one of those people who takes words on faith - I want to KNOW what things mean so that I know how they work. Thanks for giving me that info.
Thanks, John. What you said sums up exactly what I thought when I started out in photography; everyone was telling me to believe this or that, but I wanted to know the hard science and truth behind things; that's what led me to create this channel. Thanks for the feedback and I'm glad I am delivering on my promise to provide straightforward and factual content. Take care.
This was the only video I could find on RUclips that actually explained how lenses and their numbers work technically. One nitpick: in the list of drawbacks of zoom lenses it didn't mention that zoom lenses lose aperture stops with increased zoom.
I just watched a video from a guy with 900k subscribers. He scribbled on an electronic drawing screen to explain these concepts but his explanation couldn't have been more confusing! Then I come here and watch an extremely SIMPLE to understand explanation with VERY good diagrams. Your video was ten times as good as his! Thank you! Liked and Subscribed!!!
Thanks so much, I really appreciate that! I try to be as simple and straightforward as possible so I don't waste anyone's time and so only the necessary information is communicated.
This animation is so helpful I cannot express that enough. I always come back to this video when I get confused about focal lengths. 0:38 is by far the best graphic for describing this!
What I find most interesting about all this is how complex light is and makes me realize the image of the world that I myself perceive is shaped by the shape of my eyes, and not a 100% accurate representation of what reality actually looks like.
This is true. Our reality is how we perceive it, and light is one of the most fundamental aspects of how we interpret our surroundings. Cameras are interesting because they perceive light in a purely unbiased way, capturing light the way it exists naturally, not the way our brains think it does.
Honestly the best explanation I've found on the topic as I'm just beginning, other just start throwing the numbers around without really explaining too much about it, also the physics interpretation at the start really helped me understand why longer focal lengths would look the furthest and make objects look close together (rays are almost parallel at that point it's like isometric view)
Your animation art is absolutely beautiful, coupling that with the detailed yet understandable explanations and your videos are amazing. Thank you for your hard work!
New to Photography and just found your channel. The graphics and animation is amazing along with the demystifying explanation. Absolutely well done. That Focal Length and Field Of View animation at 0:36 and its explanation has hands down got to be the most concise explanation I’ve ever seem represented. So good I decided to subscribe.
Thanks a lot for the extremely intuitive and very simple explanations for the focal length. This is the first time I have got the actual impact of focal length
Totally agreed with this video... I learned most of basic and advance information's... I can't get it clearly from my friends.. But with your help.. I get more n more.. Thanks!
Honestly this is one of the best videos i have seen on this topic and explained this in a while understood. I had multiple aha moments of now i understsnd that.
Nice video!! just a point, the distortion or compression is not created by te lens itself, they are created by the physical distance between the camera and the subject.
Apalapse, I would like to thank you for this video of yours. I love the section about your explanation of the APS-C and the Full-frame camera. Now I know how to calculate the focal length of my lens when I mount them on my APS-C camera.
I'm glad you liked it! The only thing I should say is that when you switch from full frame to APS-C, the focal length itself does not change, it's only the field of view. This is just a semantics issue mostly but it's important to remember since a lot of people think that when they switch bodies the focal length of the lens also changes, making it a different lens... When you multiply the focal length by the crop factor you are just saying that on the smaller-sensor camera the lens has a new field of view of ____, since focal length is the distance from nodal point to the sensor it will never change regardless of the camera you attach it to. I just wanted to articulate this in case it helps you or anyone else. Thanks for commenting and take care!
Thank YOU. Your kind words really inspire me to keep making videos. I am glad I could help you and others. Sorry for just responding to this comment now.
Your video's are awesome - have always left camera on Auto - Now retired with time on my hands so trying to do a little better. Read a few things, saw some videos but after seeing this channel, the fog is really lifting. Thanks so much !
I'm really glad that you found this video helpful. I hope you are able to find the time to learn manual mode, the process of shooting manual is a great way to really learn how your camera works. Let me know if you need any more help or have any suggestions for future videos. Take care!
I'm interested in photography but Due to family force doing something else but I always watch vedios and get knowledge about Photography ❤️ love this Channel
I'm glad it was helpful! I try and make the videos striaght to the point with simple terms so that everyone can understand. Thanks for the feedback and good luck with your photography.
These are some of the best basic photography videos I have seen. Real clear and easy to follow. It doesn't do much good to study shooting techniques and advanced features if your not clear on the basic concepts; these videos really cleared up some misconceptions and some confusion for me so I now can move on to more advanced concepts. Thank you very much.
in case anyone got confused about the wording of "where light converges" to image sensor (like me), so I looked up the physics. Where the light converges should be the focal point, which is on the image sensor to form a clear image. focal length should be defined as the distance between the optical center to focal point instead, optical center being the place where ray light passes without any deflection
Having the same effective focal length and actual focal length does not mean the focal lengths are equal, only that the image they produce has similar dimensions. Having 50mm lens on a cropped sensor still obeys the lens equation physics of 50mm lens, it just gets cropped down.
Great video, really well explained. Only thing is telephoto lenses do not cause compression. It's the backing up of the camera and therefore the increase in distance that causes compression. You can see this with your eyes when you look out the car window on a long drive, all the objects on the horizon seem close together. Telephoto compression is a myth, it's the distance of the camera to subject that increases/decreases compression, the telephoto lenses are just able to zoom in to see it better. You can also see this if you back up a wide angle lens a whole bunch and then digital crop in, it will also have compression (albeit the quality will likely be awful but it does demonstrate this phenomenon).
Correct explanation. That was one of the mistakes I made with this video. Thanks for pointing that out and sorry for responding so late, I do appreciate your feedback.
this helped me so much. ive been trying to understand these aspects of photography for so long and this is the best video ive ever seen. it taught me about more than just focal length. thakns for going in detail about them and making it easy to understand. thank you.
Haha! Thanks for the kind words. My goal is always to try and break complicated concepts down into easy-to-understand tidbits. I'm glad you found that in this video, thanks for watching, friend! Take care and live HEPPily.
Unless I'm mistaken, at 0:28, the illustration is incorrect. It depicts focal length as the distance between the point at which light rays converge and the sensor, but it depicts the sensor as being out in the camera lens itself, instead of at the back of the camera body, where the sensor actually sits.
You are correct, technically. This is something I looked over in the illustration phase of making this video and I just noticed it now with your comment. Thanks for pointing this out.
Awesome video.....very easy to understand. Thank you for taking the time to make this video and sharing with us. learned several things from it. Once again thank you.
@@Apalapse you're right, it makes sense to use your own one. That's why I learn how to make it more professional. One day you won't hear a difference anymore))
35mm is not the lenght of diagonal (obvisously cannot be, because the diagonal must be longer than any other side, so it should be bigger than 36mm). It is a naming from film era. It comes from fact, that the film with the holes was 35mm wide. en.wikipedia.org/wiki/135_film
Thank you for the kind words and you are very welcome. I enjoy putting together these videos and helping other photographers understand important concepts.
Ignore the term "crop factor" The focal length of a lens does not ever change. It still stays the same whether you use it on a 35mm or APS-C camera. A 50mm lens is a 50mm lens. Ignore phrases that state that a 50mm lens suddenly becomes a 75mm just because you are using it on an APS-C camera. Lenses that have been specifically designed for APS=C cameras have a smaller imaging circle so there is no "crop". So what about large and medium format cameras ?
Crop factor is a term that is helpful for beginning photographers to understand. To some people it may be misleading but when explained correctly it is simply he amount of crop that occurs when a certain focal length lens is attached to any type of image sensor other than full frame. Large and medium format cameras have a crop factor of less than one (
@@Apalapse I disagree with everything you have just said. Why reference a camera / lens system that a beginner to photography may have never seen or used ? An APS-C lens doesn't "crop" anything. APS-C lenses have an imaging circle that matches the size of an APS-C sized sensor. Similarly, 35mm sized film/digital cameras use lenses that match the larger size of the frame. No-one ever talked about "crop factor" when comparing 35mm and medium format cameras, it wasn't required, so why should we use it now ?
@@alanelesstravelled8218 Whether or not APS-C is a term a beginner will know is not something you nor I can comment on. I like to think that APS-C and full frame are both terms that will ring a bell to most photographers, even if they are a total beginner, so I feel comfortable using them in my camera basics videos. While you're right in that an APS-C lens will produce an image circle large enough to cover an APS-C sensor camera, the focal length measurement is still in reference to a 35mm sensor format. Why is crop factor such a bad term? When I put a full frame lens on my full frame camera, the field of view equates to what is written on the lens body, but when I put it on my APS-C camera, the field of view is NOT the same in the files, it is increased by a factor known as the crop factor. I never said the lens itself crops anything, that's obvious; glass is glass and the physicality of the lens does not alter based on the camera it is attached to. Just because it is a new term doesn't mean it can be used effectively.
please do note that film for still photography and film for motion pictures are different. Still image film is run through the camera horizontally, and the exposed area is what we call "full frame" today. motion picture 35mm film is run through the camera vertically, leading to a smaller exposed area, which is very roughly aps-c today
Slight error. That 35 mm is not a diagonal measurement, it is the total width of the film, including the edges that have holes for manipulating the film's position. 35 mm camera film is exposed over an area that is 36 mm x 24 mm. There are also a number of APS-C lenses that will go down to 11 or 12mm without fish-eye distortion.
The focal length is a relic from the film era. When nearly all cameras were using 35mm film or 135 as is its official name. Focal length corresponds to different angle of view with different sizes of digital sensors or films. The angle of should be indicated with lenses instead of focal length but older photographers were accustomed with focal lengths and the standard 35mm films. Cameras with larger sensor have an advantage with wide angle lenses. On the other hand cameras with smaller sensor can have easily super telephoto lenses.
The optical center of the lens is not necessarily inside the lens. On wide angle lenses it is typically inside the camera body. On telephoto lenses it is by definition in front of the lens. Ultrawide senses and fisheye lenses are entirely different do grouping them is so can be confusing. Fisheye lenses produce huge distortions while ultrawide does not. Once you have used ultrawide, you cannot live without one.
Thanks for the clarification. A lot of graphics on google were wrong about this and after I did some research I realized that I made an error in the video.

The optical center of the lens is not necessarily inside the lens. On wide angle lenses it is typically inside the camera body. On telephoto lenses it is by definition in front of the lens.
Ultrawide senses and fisheye lenses are entirely different do grouping them is so can be confusing. Fisheye lenses produce huge distortions while ultrawide does not. Once you have used ultrawide, you cannot live without one.
35mm is not the diagonal of the film frame. It's the width
Thanks for the clarification. A lot of graphics on google were wrong about this and after I did some research I realized that I made an error in the video.
Thanks for the explanation
35 mm is actually the width of the film including the perforations. Also movie cameras and still cameras used the film in a very different manner.
Good point!
