using the "back" auto button

[patriciaann1]

I read an article here on DPS about how to get the best sharp images, and one of the things was to use the back auto button, which I have tried to do in conjunction with the live view on my Canon 5d mk2. I understand there is some custom functions I need to set can anyone help..

I use back button focus all the time now, love it. However, I gave up on Live view after the first try.
