Contax 159MM - Program AE Control Scale Reference; Interpreting AE Mode Combinations

Shutter

(Program
AE
Control
Scale)
The
aperture
and
shutter
speed combinations
available
in
the
Normal
Program,
High-speed
Program,
and Low-speed
Program
AE modes
are
as
shown
in
the
accompanying
scale. When the matching
aperture is
within the
working
shutter speed
range
oI 111000
sec
in
the
High-speed
Program
and
of 1/60
sec.
in
the
Low-speed
Program
modes,
the
shutter
speed LEDs
will
pulsate
at
the
respective
shutter
speeds.
lf
a
lens
with
a
different
maximum
aperture is
used, the
working range
will
vary
by the
extent
of the
light
value
difference
For
example,
if
an
1112.8
lens is
used. its

Even
when
the
aperture
ring
is
at a
setting
other
than
minimum
aperture,
the
camera
will
still operate
in
the
program
AE
mode.
However,
in
this
case,
the
camera-
selected
shutter
speed
will
work
within
a
narrower
working
range
between
whatever
smaller
aperture
you
have
selected
and the
maximum
aperture
of the
lens,
causing
the
camera-selected
shutter
speed
to
shift
under intense
lighting
conditions.
For
example,
when
set at f/g, the
working
range
will
be
narrowed
as
shown
by the
