Here it is - All said and done, the button activates focusing, instead of the shutter button. If you do not press the back button, it will continue to shoot at the focus distance that was shot last, in effect, providing you with a focus distance lock.

You can use back button focusing to solve this problem because the distance between the photographer and the subject stays the same between both shots, but the composition changes. With back button focusing, the photographer activates focus for the first shot, and then is able to recompose infinite times as long as the distance between the camera and the subject remains exactly the same.

my focus would have been locked on the wolf still and I could have shot to the side of the photographer and still got sharp shots as soon as I shewed him out of the frame.

I see we went full circle as this info was provided in the 2nd post by Scorpio a week ago..........
