I was wondering if anyone would share their settings for the Canon 7D for shooting sports action? What do you have all the C.FN's set to? What should the settings be for Flash on the 7D? I have a 580EXII and at night outdoors if there is dust in the air I see the dust (Looks like snow) how do I get rid of that when shooting? Up my F stop? Tame down the 580EXII?
