DEPTH OF FIELD—continued
Depth-of-Field Indicators
Depth of field can be read directly from the distance
scale in meters or feet with the aid of the color-coded
depth-of-field indicators engraved on the lens barrel.
Each pair of colored lines on either side of the central
distance scale index line corresponds to f/numbers of the
same color on the aperture scale. To find the depth of
field at a particular aperture, first focus the lens on the
subject while looking through the viewfinder. Then check
the numbers on the distance scale to determine the zone
of focus for the aperture in use. The three photos shown
clearly depict the changing depth of field; with the
photo to the right, the field is shallow at the f/4 setting,
while the photo at the far right shows a depth of field
extending from approximately 2.7m (9 ft) to infinity
