ya, bro u are so clear. Thank you.
This is a really good video.
Dude. This is by far the best explainer on focal length that I've seen on KZread. I'm a 25-year veteran in the art of photography, but I always like rehashing the basics every now and again. Thanks for this video!! 👍🏾
Very insightful. I learned something about focal length that I didn’t know before.
Best video on focal length on youtube hands down. Concise and to the point and ACTUALLY EXPLAINED what focal length entails and not a dumbed down version that tells you nothing. Thank you. Subbed.
3:49 to 3:53... most clear visual aid ever sir! Thank you, I never understood WHY until this very simple animation.

came across your channel few days ago. you deserve way more subscribers Dave!.. the way you explain is easy to understand, the graphical overlays are simple but effective. Great content.
Brief and simple to understand and very informative. It has answered many questions that many other longer videos on KZread could not explain. Excellent!!!!!
this is amazing. I spent soo much time watching many videos, but none of them got straight to the point like this guy. this video is informative and straight to the point. Nice one man....
This reminded me of the same topic back in my third grade in my high school. now i can connect the dots. thanks man.
I love it when content such as this gives you "Ohhhhhhhh" moment, connecting multiple concepts together forging an even stronger understanding. Thumbs up for that.
Explanation and simple graphics made this a total winner. Thank you!!
Best video on this topic. I have been looking, and no one is as clear and precise with the best examples. Thanks so much for doing this - I was pulling what little hair I have out!! Great job.
Thank you for the explanation! I watched a few other videos and couldn't completely make sense of it until yours. Great job!
I have watched literally dozens of videos on focal length trying to get my head around it and this is hands down the best explaination.
👍Good time use, not wasted at all. Love the simple but very clear overlay diagrams, along with vid focus changes, and the inversion. A keeper. Don’t recall seeing other vids use your effective overlay technique - instead they cut away to charts, sometimes hand drawn.
This video will never get old. Thank you. Clear and concise.
Thanks so much for the explanation! I was meaning to look this up sometime, and your video just came up. Great explanation!
Nobody explains this topic so great as you did. Great job!
Excellent video Dave, im in for version two of this :)..keep em coming. Huge Thanks!

Bravo! You just answered several longstanding, nagging questions I’ve had about this topic that all the textbooks don’t treat well or ignore entirely. Showing the path of the light and the point of convergence layered on an image of the camera and lens was a brilliant way to communicate this information. Thank you!
Thank you for taking the time to put the graphics on your hand movements during your excellent explanation. Tip top
Best explanation on KZread. Thank you mate.
Fantastic video. Well put together
I spend a lot of time finding a clear explanation about the focal length until I saw this vid! Loud voice plus clear explanation = great and really helpful video. Approved 😉👍
Amazing explanation! Thank you for the animations.
AWESOME.....great work and masterfully explained ! 👍
Excellent, I searched and now I found your simple explanation of what mm measurements on a lens means. Big thank you.
Simple and straight forward explanation... That is Dave's style.
Excellent my man! Been racking my brain. Thank you
A very fine refresher...Thank You Dave...
Best explanation I've heard. Great video!
I always find the right explanations from you ! Big thanks 👍
Nice explanation!! Cleared my Focal length and lens size doubts!!
Super great video with fantastic explanation, even a beginner will fully understand this
So helpful tips. Thank you Dave:)
An excellent explanation. Clear and to the point.
Man, super content: clear and compact !
Amazing bro looking for the right awnser and theory and you video was the awenser thanks so much well done explaned
Superbly clear and useful explanation. Thanks!
Awesome video and thanks for making it easy to understand! Perhaps you could even make a part II of the video where you use the same diagrams light ray diagrams to explain the field of view and equivalency of focal lengths on different sensor sizes. You alluded to it early in your video but it would be very clear when you compare for example a 200mm M4/3 lens and a 400mm FF lens with the same field of view but the m4/3 version can be so much smaller due to the focal length being shorter.
You explain very well mate, well done! Love it!
Awesome!! Thank you. Best explanation I ever heard and seen!!!
Brilliant! Good work man!
Great video with a simple explanation!
very good explanation, I always watch youtube photographers that say they don't want to jump into the math and annoy us till I figured out that they actually don't know anything about it. however, I think any person who call himself a photographer needs a basic understanding of camera electronics and optics, so great job and I am looking forward for more content like this.

Thanks Nader, I already have a few other videos similar to this on my channel but no doubt there will be even more in the future 😊
Finally someone who has explained this perfectly - thankyou!
Excellent video! Very well explained!
Excellent explanation in regards to focal length distance, angle of view, aps-c vs full frame sensor, and physical size/length of lens.
Simple, easy and best explanation. Great job dude
the brain does not compensate anything. we live hanging from the ground.
Thank you so much, this is very good explanation!
That was the best video on focal length I have ever seen. Thanks so much, I learned a lot.

Thank you so much for this super clear explanation of focal length. I finally understood it, thanks to you! Brilliant job, thank you for using those lines! 👍😁🙏
Best explanation ever ... point of convergence was deal killer. No body explained like you did. I saw 10 videos and I was all confused but not any more! Thanks!
Amazed by the explanation!!
