<Depth of field>
Depth of field for a given lens varies as follows.
Depth of field increases as the aperture is closed down, and is reduced as the
aperture is opened.
The depth of field is increased as the distance to the subject increases, and is
reduced as the distance to the subject decreases.
Depth of field for a subject in focus is greater behind than in front of the subject.
Depth of field is greater for lenses with short focal lengths, and shorter for lenses
with long focal lengths.

When a lens is focused on the subject,
objects within a range in front of, and
behind, the subject are also in focus.
This range is referred to as the "depth of
field".The aperture remains fully open in
the viewfinder, however when the aper-
ture stop-down button is pressed the
aperture is closed down to the previ-
ously set value to allow checking of
the depth of field and the fuzziness
of the background.
