Practical Use Manual

® Selecting the Shutter Speed
The figures 2 to 500 on the shutter speed scale
indicate fractions of a second. The speed ring
engages at each setting; you cannot set inter-
mediate values. Select a sufficiently fast shutter
speed for sharper pictures:
Firstly, use fast speeds for hand-held shots to avoid
camera shake. Here 1/30 second is the longest
permissible time; 1/60 or 1/125 second is safer and
more frequently used.
Secondly, use faster shutter speeds for fast
moving subjects to avoid movement blur. Thus
sports shots need 1/500 second, running children 1/
250, fast walking pedestrians 1/125, ambling people
1/60 or - if farther away - 1/30 second.
As a rule, the farther away the moving subject, the
sharper it will appear. The risk of movementblur is
also reduced by shooting in the direction of the
movement (rather than across it).
05 Time Exposures
The B setting on the shutter 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.
With 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
matching pointer, the correct exposure time 1
second (double the next exposure setting). For
long time exposures place the camera on firm
support or a tripod and use a cable release with
time lock.
® 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 shown
on the distance scale: Look up the index line of
the aperture in us to each side of the focusing
index. The distant 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 reason the most use full
snapshot settings of 6 and 20 feet at marked
in red on the distance scale. At a medium aperture
(f/8 to f/11) these settings provide extended
focusing ranges: at 6 feet from about 4'/s to 9
feet; at 20 feet from about 10 feet to infinity «.
