METERING
WITH
THE
XG-7
(Automatic
mode only)
The
"centra\-zone
weighted
overall"
meter-
ing
svstem in
your
XG-7
emp\oys
two CdS ce\\s
mounted
behind
the
pentaprism
so
that light
from
all
parts
of
the viewfield
(picture
area)
is
measured
but
influence
from
a broad
central
area
is
greatest.
Thus
the
reading
should
yield
satisfactory
exposure
without
ad
justment
as
long
as the
main
subject
area
occupies
a major
part
of
the frame.
lf
the subject
area
to
be
measured
occupies
a
relatively
small
part
of
the frame,
move
the
camera
so
that
the main
subject
fills
most
of
the frame.
Note
the shutter
speed
setting
in this
position
and
compensate
for
the
ex
posure
difference
with
the
shutter-speed/function
se-
lector
or
use manual
speeds
to
set
the
same
value
when
making
the
exposure
from
the
original
position.
Further,
if
the
most impor-
tant
area is very
much
brighter
or darker
than
the rest
of the
frame
and does
not fill most
of
it,
exposure
should
be decreased
or
increased
\^lith
the
same control
from
112
to
2 stops, the
exact
amount
varying
with
the specitic
bright-
ness difference
and
the effect desired.
(p.29).
As with
most
metering
systems,
strong
sources
of direct
light
or
other very
bright
areas
may
influence
the reading
adversaly
is
allowed
to dominate
the
frame.

Though
your
XG-7
finder
is designed
to
minimize
the
effect
on
the meter
of light
entering
through
the finder
eyepiece
under
usual
cond
itions,
care must
be
exercised
to
prevent
this
especially
if
you
wear
glasses.
Use
of
a rubber
eyecup
is further
recommended
when
the
subject
is
in
shade
and
the
camera
is in
sunlight,
when
bright
sidelight
falls
between
eye
and
eyepice,
or when
stopdown
metering
is
used,
particularly
at small
apertures
(see
p.
44).
When
viewing
is
unnecessary,
the eyepiece
cap
(see
p.
25)
can
be
used
to completely
eliminate
this
problem.)
