PROGRAMMED AUTO EXPOSURE MODE - AUTO MULTI-PROGRAM
Auto Multi-Program automatically sets
the
best combination of
shutter speed and
lens
aperture, making it
the
easiest exposure
mode to
use.
Because
lenses of
different
focal
length
handle differently at
slow shutter speeds, picture sharpness varies
with
the shutter
speed
used. The
slowest shutter speed
recommended for
any
lens
when
hand-holding the
camera
is
1/(focal
length)
of
the
lens.
With a
60mm lens, for
example,
use
1/60
sec. as
the
slow-
est
hand-held
speed. Keep in
mind, however, that
1/30
sec.
is
the lowest
recommended shutter speed
for
blur-free hand-held
shooting.
The
exposure program
line for N5005's
Auto
Multi-
Program
varies according
to the focal length
and
maximum
aperture of
the lens. The
following chart shows
how the possi-
bility of picture
blur
is reduced by avoiding slower shutter
speeds.
Auto Multi-Program chart
The EV
(exposure value) charts
demonstrate the differences
among program
lines
of various
lenses. Follow
either colored
line
to
where it intersects a diagonal
line.
This
shows the com-
bination of aperture (vertical line) and shutter speed (horizontal
line) that
will automatically be selected at each EV brightness
level.
