The focus assist lamp is designed to provide a bit of illumination where there is no light. Unfortunately, it has a very limited range and often, the AF light doesn't improve contrast. With longer lenses, the chances are that you're far enough away from the subject that the AF lamp is ineffective. When it's on, the AF system seems a little less aggressive in terms of hunting for focus and will often miss.
