:;:
Use of M-class bulbs is not allowed
.
If used
,
the camera may be
broken.
Caution:
You can use infrared synchronizers that are designed to synchronize
cordless flash and camera
,
but practically all of these devices are
equipped with built-in flash
.
A few of them
,
however, operate on built-in
LEOs and slow-response receivers
.
Be careful when you use these time-
lag units because
they
can sometimes fail to fire the flash
.

USING THE FINDER HOOD
(1) Expanding the hood (Fig. 24)
Just lift the hood cover up and it will spring into position by
itself.
Opening Notch
(Fig. 24-A)
(2)
Using the magnifier (Fig. 25)
When you look at the camera
from the
back,
you will see a small
lever
near the Opening Notch in the right
hand
side of the Finder Hood. To flip
up the
Magnifier,
just slide this lever to the right. To put it
away,
push
down the Magnifier
Board.

Folding down the hood
After putting the Magnifier
away,
place
your thumbs against both sides
of the
Hood
along
the
hinges and push them inward
.
That's
all.
The
Hood will collapse and
fold
down by itself.

Mounting and dismounting the finder hood (Fig. 26)
To dismount the Finder
Hood,
slide
it
toward the lens while pressing in
two Finder Lock Release Buttons.
To mount,
insert the projected portion of the Finder Hood
into the
recess
on the camera
body,
and slide it toward the holder.

8. FRAMING YOUR PICTURE (Fig. 27)
The frames for horizontal and vertical composition are marked out with
black lines in the
viewfinder.
These
are used by revolving the Roll
Film
Holder
ill
to the desired position.
When the Roll
Film Holder
ill
is revolved into
horizontal
position
,
the
Framing Indicator will appear in the top and bottom of the Finder and
when it is revolved into vertical position, the Framing
Indicator
will ap-
pear in the left and right sides of the Finder.
Framing Indicator
(Fig. 27-A)
•
If you are using
Instant Film
Holder
D,
you can attach a framing mask
to
it
that
interlocks with the
Finder
's
Framing
Indicator.
•
If you are using Instant Film Holder
I
,
remember the Framing
Indica-
tor will remain fixed in vertical frame position
only.
•
If you are using Finder Screen for 6x6cm and 6x4.5cm size
,
you will
not be able to see the Framing Indicator. Remember that the position
where vertical
Film Holder
position is revolved
90°
is the horizontal
position
.
Notice for mirror rejection:
•
Since the mirror length is restricted by the body construction
,
depend
-
ing on how far the
bellows·
is drawn out, you may not be able to see
the upper edge of the Finder image
.
With a 250mm focal-length
lens
or
longer,
the upper edge of the Finder image will be rejected even if
the lens is set to
infinity.
•
On account of the restricted
mirror,
the upper edge of the Finder im-
age may
be
rejected when
camera-front
movements are employed
(particularly tilt ups and
falls)
.
•
Moreover,
since the image circle of the GX680
ill
's interchangeable
lenses
have
room to spare even when maximum camera-front move-
ments
are
employed, the
upper edge of
the
Finder image will register
on the film even if it is rejected by the mirror. With a 50mm lens
,
the
upper edge of the Finder image will be rejected when maximum cam-
era-front movements are employed
.
• To
eliminate
finder-image
edge blur
resulting
from mirror rejection of
the image when a
long
focal length
lens
is used
,
just set the camera
front to the
"rise"
position
.
9. FOCUSING THE LENS (Fig. 28)
While looking at the image in the viewfinder, bring it into focus by
turning
the Focusing Knobs in both sides of the camera.
After
focusing,
use the
Focus Lock
Lever to lock the focus in pl ace
.

:;:
The GX680
ill
is equipped with a function for the front
movements.
To
permit camera-front movements with the lens set to
infinity,
the inter-
changeable lenses of the GX680
ill
are not provided with an infinity
stop.
