8. Depth of field
The image of a subject is sufficiently sharp
over a range of distances in front of and
behind the focused distance. This depth of
field zone is shown on the depth of field
scale 3:
Look up the marks of the aperture in use to
each side of the focusing index The figures
on the distance ring 22 opposite these marks
then indicate the sharply covered subject
range
Depth of field is particularly desirable for
candid snapshots, sports photography with
rapidly changing subject distances, and for
scenes extending in depth. For this reason
the most useful snapshot settings of 6 and
20 feet (or 2 and 6 at meter scale) are marked in red on the distance ring 22. At a medium aperture (f/8 to
f/11) these settings provide extended focusing ranges:
Scale at
Distance range in focus
6 feet
(2 m)
from about 4'l/2" to 9 feet
( from about 1.5m to 3m)
20 feet
(6 m)
from about 10 feet to infinity
(from about 3m to infinity)
For distant views with near foregrounds set the infinity marking "oo" opposite the aperture in use on scale
3. That extends the depth of field to the nearest possible point in the foreground.
