Depth of Field
Depth of field refers to the zone of acceptable focus
extending in front of and behind the plane of sharpest
focus. Within
thi~
zone, image blur is negligible and
everything can be considered as being in sharp focus.
To observe the depth of field with the PC-Nikkor lens,
it is necessary to manually set the diaphragm to the
required shooting aperture; for procedures, refer to
"Setting the Aperture" on page 6.
Depth of field can also be determined by reading the
color-coded depth-of-field indicators engraved on the
lens barrel opposite the distance scale. Each pair of
colored lines corresponds to an f/number of the same
color
engr-
a ved on the lens front rim. To find the
depth of field at a particular aperture, focus the lens
on the subject and then check the numbers on the
distance scale opposite the colored lines that match
the color of the preset shooting aperture
setting.
When in doubt about depth of field for a critical
shooting situation, refer to the tables on pages 20 and
21 of this instruction manual.
