Yes you can use both. Its not either/or unless you configure it that way.
So with this camera there are three options for focus?

You will need to deactivate the AF on half pressing the shutter button. I think some of the responses here could be clearer. Otherwise there is no point having the back button activate focus.

Thought so.

I would strongly suggest you set the camera to P and enjoy yourself.

That is incorrect. I use back button focus on my 7D II much of the time. I have the AF On button set to automatically switch to AI Servo when depressed, whereas the shutter button is set for One Shot. When I want One Shot I use the shutter button, when I want AI Servo for sports or action I use back button focusing. I also have the * button set for a second choice for back button focusing with different shooting parameters, and a different focus point zone, primarily for birds in flight. As long as the back buttons are kept depressed they take focus away from the shutter button and automatically apply my specified shooting options such as a specific focus point or zone selection and a switch to AI Servo. Disabling AF on the shutter button is just one approach to BBF on a 7D Mark II and is definitely not necessary to take advantage of that feature.

I agree if he has no intention of learning how to get the best from his camera and P mode meets all his shooting requirements. I wouldn't suggest using it for sports, birding or wildlife though, or anything else that moves quickly or erratically for that matter. I also wouldn't suggest using P mode for low light conditions. I personally only use P mode when I just want to get some quick snaps and don't want to spend time adjusting for the best shot.

I'm not sure I understand your question. Can you be more specific. There are actually 13 different options for AF focus but none of them are related specifically to back button focusing but some of them are specific to AI Servo. I assume you are referring to my use of back button focusing on the 7D Mark II but it's still unclear to me exactly what you're asking.

He is incorrect. Deactivating focus on the shutter button is only one approach to using back button focusing on the 7D Mark II. With a less configurable camera with fewer focusing options for the back button it might seem the only way to go. But on this camera it most assuredly is not. See my response to him a few posts above this one.

Oh, I thought I could use both. I like the idea that I can hold my AF button down while following my granddaughter around the field and stay in focus. I missed a great catch she made (she almost went over the fence) because I lost focus.
Thanks
Thanks
Does your camera have a "Continuous Auto Focus" (AFC on Sony) mode? If you are trying to stay focused and follow the action, this is the way to go ...., much easier than holding any buttons down as the camera continually keeps the subject in focus.

Okay.
(Saw that.)(Don't have a 7d, wondering how many options may be different between models.)
Thanks!

Depends. What were the other settings of the exposure triangle? And, for action photography, a higher ISO is always warranted, even on a sunny day, since you are catching movement.
I read through the thread and cannot find an answer to this question. Were you in full manual, AV, TV or some other mode? Do you have any limits set on aperture, shutter speed or ISO? What lens were you using?
Could you post one of the "failed" images?

It's hard to say since you didn't save any of the pics for us to view.
