    👍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.

    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!

    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.

    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.
