Selecting
the Shutter
Speed
The figures
2 to 500
on the
shutter
speed scale
indicate
fractions
of
a second.
The speed ring
engages
at
eadr
setting;
you
cannot set
inter-
mediate values.
Select
a sufficiently
fast shutter
speed
for
sharper picrures:
Firstly,use
fast
speeds
for hand-held
shots
to avoid
camera shake.
Here
7l3O
second
is the
longest
permissible
time;
1/60
or 11725
second
is safer
and
more frequently
used.
Secondly,
use faster shutter
speeds
for fast
moving subjects to avoid movemenr
blur. Thus
sports shots need 1/500
second,
running
children 11250, fast walking pedestrians
11125,
ambling
people
7160 or
-
if farther away
-
1/30
second.
As
a rule, the farther
away the
moving
subject, the sharper
it will appezr.
The risk of
movement
blur is also reduced
by shooting
in
the direction
of the movement
(rather
than
across it).
@
Time
Exposures
The
B setting on the
shutrer speed wheel pro-
vides
time
exposures
of any required
length.
Keep the release
button depressed
for the
re-
quired
exposure time.
The shutter
closes when
you
let go
again.
\fith
time exposures
you
can also take
shots
in very poor
light which
is too
weak for
an
exposure
meter reading.
As a special
case, if
you
arrive
at the
B
setting
by
lining up
the
matdring
pointer, the correct exposure
time is
1 second
(double the next
exposure setting).
For long time exposures
place
the camera
on a
firm support
or a tripod
and use a cable release
with time lod<.
@
Depth of
Field
The image
of
a
subject is sufficiently
sharp
over
^ range of
distances in front of and
behind
the
focused
distance. This
depth of field zone is
shown on the distance scale:
Look
up the index line of the aperture
in use
to eadr side of the focusing
index.
The
distance
figures
on the focusing scale opposite these
lines then indicate the sharply
covered
subject
range.
Depth of field is
particularly
desirable for can-
did snapshots, sports
photography
with
rapidly
changing subject
distances,
and for scenes
ex-
tending in
depth.
For this reeson the most use-
ful snapshot
settings of 6
and 20 feet are
marked in
red on the distance scale.
At a me-
dium aperture
(f/8
tof/l1) these settings provide
extended
focusing ranges:
^t 5 feet from about 41/z to 9 feet;
at 20 feet from about
10
feet to infinity
-.
