DEPTH OF FIELD 00 15 10 9 8 7 6 Depth of field is the area of acceptable sharpness in front of and behind the point of focus. The depth of field becomes progressively greater as the lens opening becomes smaller. The distance at which the lens is focused also affects the depth of field: it increases as you get further away. The focal length of the lens is another factor to determine the depth of field. The shorter the lens, the greater the depth of field. • 34 with 5Omm f/2.O 4 131 2 f/2.0 f/5.6 f/11 f/22 1 0 Distance
