When you focus the camera on a subject, there is a
certain distance in front and back of the subjects with in
which other objects will also appear sharp. This is known
as the" Depth·of-Field" and it varies with the aperture.
The smaller the aperture, the greater the Depth-of-Field.
The Depth -of-Field Scale will be
found on the lens barrel. With the
camera focused on 2 meters, the
Depth of Field indicated by the
scale for an aperture of f j 16 is
from 1.4 meters to 3.8 meters.
