METER COUPLING RANGE The red area in the table indicates the coupling range of the meter, and should not be interpreted as the camera's total range of f/stop-shutter speed combinations. As you will note from the table below, with an ASA25 film, you may use any shutter speed from 4 sec. to 1/1000 sec., the actual shutter speed depending upon the aperture being used. The total range of the aperture settings is, of course, determined by the minimum and maximum apertures of the lens being used. For example, with the 50mm f/1.4 lens and ASA100 film, an aperture from f/1.4 (the maximum aperture of this lens) to f/22 (the minimum aperture) may be used with any shutter speed from 1 sec. to 1/1000 sec.

METER
COUPLING
RANGE
The
red
area
in
the
table
indicates
the
coupling
range
of
the
meter,
and
should
not
be
interpreted
as
the
camera's
total
range
of
f/stop-shutter
speed
combinations.
As
you
will
note
from
the
table
below,
with
an
ASA25
film,
you
may
use
any
shutter
speed
from
4
sec.
to
1/1000
sec.,
the
actual
shutter
speed
depending
upon
the
aperture
being
used.
The
total
range
of
the
aperture
settings
is,
of
course,
determined
by
the
minimum
and
maximum
apertures
of
the
lens
being
used.
For
example,
with
the
50mm
f/1.4
lens
and
ASA100
film,
an
aperture
from
f/1.4
(the
maximum
aperture
of
this
lens)
to
f/22
(the
minimum
aperture)
may
be
used
with
any
shutter
speed
from
1
sec.
to
1/1000
sec.
