Different distances ... WebAug 21, 2015 · The F-Stop controls the depth of field. A smaller F-stop number will result in more critical focus, with in objects closer to the camera or further away form the focus point getting blurrier faster. A larger F-stop number will result in sharper objects in front or away from the focus point. Setting the focus point with an object: EDIT:
