I have a first generation Canon XL-H1. I notice that in some lighting situations it is impossible to get a good focus when shooting in the HD mode. This most recently happened when shooting in front of a green screen, and the people simply looked soft no matter how many times we zoomed in and did a manual focus. I blamed the look on the monitor at the time, but sure enough, back in editing it looked totally soft all the way through. Does anyone have any ideas here? Thanks.
