About the depth of field
The depth of field is the in-focus range, measured from the distance behind a subject to
the distance in front. The depth of field can vary with the iris (F value) and the focal
length. Lowering the F value (large iris) reduces the depth of field. Raising the F value
(small iris) provides a larger depth of field. Zooming in telephoto position offers a
smaller depth of field while the depth of field in the wide-angle position is greater.
