Focusing

Why is focusing important?  What is the best way to focus a video camera?

    Focusing is important because having a shot be out of focus means that it is blurry and you can't properly see whatever is in shot. Focusing manually is important because it'll allow you to make camera movements and zoom in without worry of going out of focus. The best way to focus a video camera is to zoom in on the subject—if it is a person, you should zoom in on their eyes—before adjusting the focus ring or wheel on the camera until the subject is in focus. This is the best way as it allows you the freedom to zoom in and out without the subject going out of focus.
