You do understand that you only have to press the back button once to focus and not hold it in, right? And to shoot, all you have to do is press the shutter release. So, if you were to let your guard down, and take the camera off your eye or put it down all together, all you need to do is pick it up and start shooting away... without having to refocus at all... not even with the back focus button.
Hope that\'s more clear.
AHHHHH! I never realised this! So even if I switched subject matter and distance?
