    Although I knew just about everything in this video and it's a nice reminder of certain details, something's bugging me out : I shoot event with a 50mm on my Nikon DX format camera… and, it's definitely not an 80mm equivalent, because – as you pointed out – it is not. It's a cropped fov of a 50mm lens. That closes the gap just right between me and the performers when I just on the edge of the stage (I'm a concert photographer).
    Just wanted to mention this, because it's a bit confusing, as you talk about the fact that the focal don't change, but then say that a 50mm lens is the same as an 80mm lens on APS-C… that's not true.
    I never though about it, but just got why I love my 50mm lens on APS-C so much… the fov never changed… LOL

  18. Carolus Magnus says

    I never got this until I understood that this is basically the same thing as FOV in first person shooters. 😀

    thanks, i have Canon EOS 1300D with kit lens and this video is very helpful for upgrading my lens. i have some idea about full frame and aps-c perspective ( lens) now it is crystal clear.

  26. Cindered Bones says

    You've taught me more in 10 minutes than I did during a year at school… Thanks so much!

  27. skorpioflo says

    I really needed this lesson, crystal clear explanation. Thank you very much!

  28. M Haddada says

    So you mean the full frame is the best .

  29. bobby V says

    thank you so much for this explanation. this made it much easier to understand

  30. Tom8Tom says

    What's the dirrence between AF-S and EF-S? I cant remember if you covered it in the video.

  31. Akash Singhal says

    All light rays do not intersect inside the lense at the optical centre. Light rays are refracted throughout the cross section of the lens to intersect at the focal point, where then your camera sensor is!

  32. Scott Moszkowicz says

    This is what I was looking for. Someone that can explain and show examples. Bravo

  33. Forever Pondering says

    What a great video. You explained everything so simply

  34. Comeback Kid90 says

    Dude, I let the video play without looking at it, and I thought one of my Tim Ferriss podcasts started playing. Your inflections and the clarity at which you can explain the subject is just as precise as his….well, the way you can explain THIS subject….I don't think he's given any tutorials on photography… :D.

    Great tutorial and thank you!

  35. SkaiSharku says
