Depth-of-Field

The depth-of-field varies according to the aperture. The smaller the aperture (f/8, f/11, f/16...) the greater the depth-of-field; the larger the aperture (f/8, f/5.6,...) the smaller the depth-of-field. To take pictures which are sharp from foreground to infinity or when taking snapshots, the focusing range is extended or depth increased by using a smaller aperture. When the subject is to stand out, with the background out of focus, a larger aperture is appropriate.

The depth-of-field scale on the lens indicates depth-of-field in terms of the distance between subjects on both sides of the scale. For example, when a 80mm lens is stopped down to f/22, respectively, all objects located within the ranges shown in the illustrations above will be sharp.

*Refer to the instructions attached to individual lenses for specific depth-of-field tables.
