  • Dude. This is by far the best explainer on focal length that I've seen on KZhead. 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!! 👍🏾

  • 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.

  • 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.

  • 👍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.

  • 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.
