    Tony this was a fantastic demonstration of back button focus and why you should use it. I'm kind of new to this and this was so helpful!!

    Hi Tony & Chelsea! I found this tutorial only today and found it very interesting … I have one question : i have a Canon 6D mk2. Do you think that AF-C on my camera is reliable enough to be used as shown in your video? Or is better to switch between AF-S and AF-C depending on the subject? I had previosuly a fuji xt1, and i remember that the AF-C was always hunting for focus if pointed at a stationary subject …

    Thanks

    Can someone explain to me what is the difference between this method and just leaving it in continuous focus and using shutter button focus?

  5. Falkwings says

    Thank you for this video, it is so freaking useful!

  6. Christopher Banning says

    Is back focusing needed for sony now days

  7. NorthernOtyg says

    I still like the regular shutter focus, and since it takes me about 0.5 seconds to switch to continuous on my Fuji, there's no reason personally to use back-button focus. I'll be in single mode usually, with normal shutter focus, half hold to recompose, and if I need continuous mode, I just flick a hardware switch without looking and it's done.

    No.

  9. Daktari says

    WHAT!!!!! Why was I never told about this!!! I have Read Books on focusing, I have them right now, and This is the first time I’ve heard about the back focus button. I’m kinda pissed right now. Lolo.

    Nice, thank you sir for this info 👍 – im a beginner photographer

  11. Thomas Nichol says

    Does the Canon AI – Focus function do the same thing? That's meant to switch from on shot to servo.

  12. Zoran Randjelovic says

    I am confused :/

  13. studio7 says

    Superb…..

  14. Rodel Sangalang says

    Tony/Chelsea: do you think BBF is still necessary with newer technologies like AF-lock, eye AF, or face detection? Love your vids and books BTW! 🙏🏽.

  15. hitmhard says

    Why not use AI servo the whole time??

  16. Chris Taylor says

    I have an ancient canon t1i and I have been using back button focus since a couple months after I got it…

  17. dfg297lpopdirk says

    if your in continuous focus wether she is running or still you get the same result why complicate it ??

  18. Dennis Maher says

    Still don’t understand a word he said, I know he is only pressing one of two buttons, But which one does he press and which on does he let go?

  19. migkiller175 says

    Is there a way to apply that to a Fuji X-t20?

  20. Rial Mondal says

    Can't you just use ai-focus instead? If you use ai-focus, you can recompose like you normally would in single-shot af, and track the subject like you would with continuous

  21. James Golden says

    Thank you dearly 🙏

    I was waiting for the ball to hit him. Or maybe it did and he edited it out 🤔
