EXPOSURE MEASUREMENT 40 1Th R•d Orag• Green Orange Rai When the rapid-wind lever is pulled out 20° and the shutter button is depressed halfway, the exposure meter is turned ON. Turn the aperture ring to get a proper LED exposure read-out in the viewfinder. On the right-hand side of the viewfinder, appear the preselected shutter speed plus two adjacent speeds (e.g. "60" and "250" in the case of "125") on a transparent disk which protrudes slightly into the focusing screen area. On the right-hand side of the shutter speeds shown, there are 5 LED dots which are normally not visible. If you depress the shutter button halfway and the exposure is correct, the central green dot will illuminate. If the exposure is 1/2 EV over, the orange dot next to "250" (in the above example) will glow; as will the dot next to "60" in the case of 1/2 EV underexposure. If it is 1 EV or more over or under, the appropriate red dot will glow as a warning for adjustment of either the f-stop or the shutter speed, unless you want to make intentional over or underexposure. 14•

meter
is
turned
ON.
Turn
the
aperture
ring
to
get
a
proper
LED
exposure
read-out
in
the
viewfinder.
On
the
right-hand
side
of
the
viewfinder,
appear
the
preselected
shutter
speed
plus
two
adjacent
speeds
(e.g.
"60"
and
"250"
in
the
case
of
"125")
on
a
transparent
disk
which
protrudes
slightly
into
the
focusing
screen
area.
On
the
right-hand
side
of
the
shutter
speeds
shown,
there
are
5
LED

of
1/2
EV
underexposure.
If
it
is
1
EV
or
more
over
