I am old school. I still like to shoot stills with the shutter button. I have never disabled focus from the shutter and use the BBF all of the time for Ai Servo.
You must not be reeeally old school, as I am. In the days of manual focus, mechanical no-electric (except the meter) cameras, focus was absolutely independent of the shutter button. You could PRE-focus, and the camera was ready for a shot immediately...think pole vaulter going over the bar. By taking focus function completely off the shutter button, you can prefocus and not risk 'danger' of the camera trying to change focus at the time of the shot. As Lester put it (and his statement fits my history 100%),
"I went from full manual film to the 20D, so the idea of the AF operation bring on the same control as the shutter release is something I could not cope with; I changed to BBF straight off as being more natural....Several bodies down the line and I still can't get on with shutter button activation of AF or one shot."
While turning the lens switch to 'MF' instead of its usual 'AF' effectively allows you to prefocus and not worry about refocus, unfortunately then you have the need to find & change that switch first, if you suddenly see a photo worthy incident at a different location.
