Back Button AF?

............... I guess I'm a recovering BBF-aholic.

My prediction............​... you'll be back off the wagon in short order!

I'll just mention, because no-one else has, that it may take a few days to get used to it. Once you do though, you'll wonder, like others have said, why they ever put focus control on the shutter button.

One thing you do have to remember is that if you give your camera to someone else to take a shot, you'll have to put it back to green box or one of those other preset auto functions to return focus to the shutter button for them.

Tried It, couldn't get used to it, didn't like it...

reverted back to Shutter Button Focus which I Find more intuitive than BBF

However, I may be tempted to try BBF when shooting static subjects and using a tripod but for photographing my normal moving subjects of Wildlife, Birds, Butterflies, Aircraft I will keep using SBF.....

Started using BBAF when I got my Rebel T3 a few years ago. I like knowing that the focus is fixed instead of accidentally lifting my finger a hair off the shutter and then having the camera refocus when I go to take the shot, resulting in the camera focusing somewhere where I didn't intend.

Am in the used to use BBF not any more camp for a few reasons.

Since having the 7D2 and having the joystick to change focus points its nice having the thumb free. Having exposure compensation in "M" and having set the lever behind the joystick to exposure compensation so its nice to have the thumb free. Changing focus area selection modes, again thumb free (far right button). I didnt like the lever for this as it only went in one direction unless I missed something.

Also having read somewhere that Canon recomends using one shot for stationary targets and in low light I have the "AF on" set to change to one shot from servo. This can be used to focus and recompose if needed.

I just found my thumb had enough to do with apeture, compensation focus points and area selection that I went back to shutter button and I find it the most comfortable for me.

. . . So do you or don't you and why / why not?

I've used BBF for year because, for me, it works as an easy way to mentally and physically separate the decision of focus from exposure and composition.

You are ALL WRONG.

.... When using BBF I notice an increased tendency to get blurry pics from camera shake as I "slap" that shutter button to get images.

Well, I'll take the bait, it does appear that BBF is not best for you. We should not argue that. However, as you stated, it looks like the issue you have is far from a universal one.

I've got another example, one of the best bird flight photographers I know* uses and advocates shutter AF, NOT BBF,

So different strokes for sure!

Does the logo belong on the front or back?

Hmmmm.....let's see...I'm gonna say it should go on the back

How about having it large on the front, and then smaller on the back right shoulder. Lol

I just want the coffee mug. T-shirts make me appear closer than I actually am.

I also use BBF, and have since I read a post on this forum about it, maybe 5 years ago. It's like second nature now, and when I get a body, one of the first things I do is set up BBF.
Plus all the cool guys use BBAF, so naturally I do to.

Also, I do have BBF set up on my A6000. It works great as well.

Until my health deteriorated badly I was an instructor with the local Air cadet unit. One of the things I did was take the photos at many of the events. At one event on of the youngsters wanted to have a go with the camera, so i let him pick it up and have a play. When the AF didn't operate when he pushed the shutter button he asked, but as a challenge I told him to figure it out for himself. It didn't take much button pushing at all for him to figure it out. I tend to find that most people can actually manage to push two buttons in order to take a photo, especially if you show them what is required.

I've never used it, and probably never will...
